Description of Business | Description of Business Capnia, Inc. (the “Company”) was incorporated in the State of Delaware on August 25, 1999 , and is located in Redwood City, California. The Company develops and commercializes neonatology devices and diagnostics. The Company also has a therapeutics platform based on its proprietary technology for precision metering of gas flow. On September 8, 2015, the Company established NeoForce, Inc. ("NeoForce"), a wholly owned subsidiary of the Company and acquired substantially all of the assets of an unrelated privately held company NeoForce Group, Inc.("NFG"). NeoForce develops innovative pulmonary resuscitation solutions for the inpatient and ambulatory neonatal markets. On April 27, 2015, the Company established Capnia UK Limited, a wholly owned foreign subsidiary in the United Kingdom. Capnia UK Limited began sales and marketing operations in the first quarter of 2016. The Company’s first diagnostic product, CoSense ® , aids in diagnosis of excessive hemolysis, a condition in which red blood cells degrade rapidly. When present in neonates with jaundice, hemolysis is a dangerous condition which can lead to adverse neurological outcomes. CoSense has 510(k) clearance for sale in the U.S. with a specific Indication for Use related to hemolysis issued, and has received CE Mark certification for sale in the European Union (“E.U.”). CoSense is commercially available in the U.S. In addition, the Company is applying its research and development efforts to additional diagnostic products based on its Sensalyze Technology Platform, a portfolio of proprietary methods and devices which enables CoSense and can be applied to detect a variety of analytes in exhaled breath and other products for the neonatology market. The Company has also obtained CE Mark certification in the E.U. for Serenz, a therapeutic product candidate for the treatment of symptoms related to allergic rhinitis (“AR”) (see Note 10). |

Liquidity, Financial Condition and Management's Plans | Liquidity, Financial Condition and Management’s Plans The Company had a net loss of $3.2 million for the three months ended March 31, 2016 and has an accumulated deficit of approximately $89.4 million at March 31, 2016 from having incurred losses since its inception. The Company has approximately $5.0 million of working capital at March 31, 2016 and used $ 4.0 million of cash in its operating activities during the three months ended March 31, 2016. The Company has financed its operations principally through issuances of debt and equity securities. On July 24, 2015, the Company entered into a Common Stock Purchase Agreement (the "Aspire Purchase Agreement") with Aspire Capital, LLC ("Aspire") which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire is committed to purchase up to an aggregate of $10.0 million in value of shares of the Company’s Common Stock over the 24 -month term of the Aspire Purchase Agreement. As of April 4, 2016, the restrictions on the use of the Aspire Purchase Agreement imposed by the Sabby Purchase Agreement expired. On October 12, 2015, the Company entered into a Securities Purchase Agreement (the “Sabby Purchase Agreement”) with funds managed by Sabby Management, LLC ("Sabby"), to purchase up to $10 million worth of Series A Convertible Preferred Stock (the “Series A Preferred Stock”). The sale of the Series A Preferred Stock closed in two separate closings. On October 15, 2015, the date of the first closing, the Company received proceeds of approximately $4.1 million , net of $0.4 million in estimated expenses. Upon the second closing on January 8, 2016, the Company received proceeds of approximately $5.0 million , net of $0.5 million in estimated expenses. The Company expects to continue incurring losses for the foreseeable future and may be required to raise additional capital to pursue its product development initiatives and penetrate markets for the sale of its products. Management believes that the Company's commercial products, including CoSense, the other neonatology products and Serenz, and the distribution strategies implemented will begin to generate meaningful revenue and corresponding cash in the near term. In addition, the Company has been successful over the last 12 months in raising additional capital, including closing pursuant to the Aspire Purchase Agreement and most recently in January of 2016 with the second closing pursuant to the Sabby Purchase Agreement. Management believes that the Company has access to capital resources through possible public or private equity offerings, debt financings, corporate collaborations or other means; however, the Company has not secured any commitment for new financing at this time nor can it provide any assurance that new financing will be available on commercially acceptable terms, if at all. If the Company is unable to secure additional capital, it may be required to curtail its development of new products and take additional measures to reduce costs in order to conserve its cash in amounts sufficient to sustain operations and meet its obligations. These measures could cause significant delays in the Company's efforts to commercialize its products, which is critical to the realization of its business plan and the future operations of the Company. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies There have been no material changes to the significant accounting policies during the three months ended March 31, 2016, as compared to the significant accounting policies described in Note 3 of the “Notes to Consolidated Financial Statements” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Below are those policies with current period updates: Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly the Company's financial position as of March 31, 2016 and results of its operations and cash flows for the three months ended March 31, 2016 and 2015. The interim results are not necessarily indicative of the results for any future interim period or for the entire year. Certain prior period amounts have been reclassified to conform to current period presentation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2015 included in the Company's Annual Report on Form 10-K. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of expenses in the financial statements and accompanying notes. Actual results could differ from those estimates. Key estimates included in the financial statements include the valuation of deferred income tax assets, liability and equity instruments, stock-based compensation, acquired intangibles, contingent earn-out consideration, and allowances for accounts receivable and inventory. Inventory As of December 31, 2015 and March 31, 2016, the Company’s inventory was comprised of the following (in thousands): March 31, 2016 December 31, 2015 Raw materials $ 290 $ 106 Work-in-process 267 399 Finished goods 96 46 Total inventory $ 653 $ 551 Inventory is stated at the lower of cost or market under the first-in, first-out (FIFO) method. Intangible Assets Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which range in term from 5 to 12 years. The useful life of the intangible asset is evaluated each reporting period to determine whether events and circumstances warrant a revision to the remaining useful life. Goodwill The Company tests its goodwill for impairment annually, or whenever events or changes in circumstances indicate an impairment may have occurred, by comparing its reporting unit’s carrying value to its implied fair value. Impairment may result from, among other things, deterioration in the performance of the acquired business, adverse market conditions, adverse changes in applicable laws or regulations and a variety of other circumstances. If the Company determines that an impairment has occurred, it is required to record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. In evaluating the recoverability of the carrying value of goodwill the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the acquired assets. Changes in strategy or market conditions could significantly impact those judgments in the future and require an adjustment to the recorded balances. There was no impairment of goodwill for the three months ended March 31, 2016. Such goodwill is not deductible for tax purposes and represents the value placed on entering new markets and expanding market share. Common Stock Purchase Warrants and Other Derivative Financial Instruments The Company classifies Common Stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that certain freestanding derivatives, which principally consist of Series A, Series B, and Series C Warrants to purchase Common Stock, do not satisfy the criteria for classification as equity instruments due to the existence of certain cash settlement features that are not within the sole control of the Company or variable settlement provision that cause them to not be indexed to the Company’s own stock. Due to certain provisions contained in the Series B Warrant agreement that provides for the Company potentially issuing an unlimited number of shares upon exercise, the Company had adopted a sequencing policy that reclassified contracts, with the exception of stock options, from equity to assets or liabilities for those with the latest inception date first. The Company had evaluated the issuance of securities as to reclassification as a liability under this sequencing policy through February 12, 2016, the date that the Series B Warrants expired. Recent Accounting Pronouncements There have been no new accounting pronouncements or changes to accounting pronouncements during the three months ended March 31, 2016 as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 that are of significance or potential significance to the Company. |

Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to the short-term nature of these items. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows: • Level I Unadjusted quoted prices in active markets for identical assets or liabilities; • Level II Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and • Level III Unobservable inputs that are supported by little or no market activity for the related assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands): Fair Value Measurements at March 31, 2016 Total Level 1 Level 2 Level 3 Assets Money market fund $ 3,975 $ 3,975 $ — $ — Liabilities Series A warrant liability $ 558 $ 558 $ — $ — Series C warrant liability 219 — — 219 Total liabilities $ 777 $ 558 $ — $ 219 Fair Value Measurements at December 31, 2015 Total Level 1 Level 2 Level 3 Assets Money market fund $ 3,804 $ 3,804 $ — $ — Liabilities Series A warrant liability $ 1,213 $ 1,213 $ — $ — Series B warrant liability 865 — — 865 Series C warrant liability 462 — — 462 Total common stock warrant liability $ 2,540 $ 1,213 $ — $ 1,327 The Series A Warrant is a registered security that trades on the open market. The fair value of the Series A Warrant liability is based on the publicly quoted trading price of the warrants which is listed on and obtained from NASDAQ. Accordingly, the fair value of Series A Warrants is a Level 1 measurement. The fair value measurements of the Series B and Series C Warrants are based on significant inputs that are unobservable and thus represent Level 3 measurements. The Company’s estimated fair value of the Series B Warrant liability is calculated using a Monte Carlo simulation. Key assumptions include the volatility of the Company’s stock, the expected warrant term, expected dividend yield and risk-free interest rates (see Note 5). The Company’s estimated fair value of the Series C Warrant liability is calculated using the Black-Scholes valuation model. Key assumptions include the volatility of the Company’s stock, the expected warrant term, expected dividend yield and risk-free interest rates (see Note 5). The Level 3 estimates are based, in part, on subjective assumptions. The agreement to pay the annual royalty in the NFG acquisition resulted in the recognition of a contingent consideration, which was recognized at the inception of the acquisition. Subsequent changes to estimate of the amounts of contingent consideration to be paid will be recognized as charges or credits in the statement of operations. The fair value of the contingent consideration is based on preliminary cash flow projections, growth in expected product sales and other assumptions. Based on the assumptions, the fair value of the royalty was determined to be $153 thousand at the date of acquisition and $172 thousand as of March 31, 2016. The fair value of the royalty was determined by applying the income approach, using several significant unobservable inputs for projected cash flows and a discount rate of 20% commensurate with the Company's cost of capital and expectation of the revenue growth for products at their life cycle stage. These inputs are considered Level 3 inputs under the fair value measurements and disclosure guidance. On January 13, 2016 we entered into an agreement to sublease our excess space located in Redwood City. By the end of February we removed all equipment, furniture and fixtures being stored in this excess space and ceased use of this space. The fair value of the cease-use liability was calculated using the remaining lease payments, offset by future sub-lease payments, offset by deferred rent amortization, and discounted to present value using our current cost of capital of 20% . These inputs are considered Level 3 inputs under the fair value measurements and disclosure guidance. During the periods presented, the Company has not changed the manner in which it values liabilities that are measured at fair value using Level 3 inputs. The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers within the hierarchy during the periods presented. The following table sets forth a summary of the changes in the fair value of the Company’s Level 1 and Level 3 warrants, which are treated as liabilities, as follows (dollars in thousands): Series A Warrant Series B Warrant Series C Warrant Number of Warrants Liability Number of Warrants Liability Number of Warrants Liability Balance at December 31, 2015 2,425,605 $ 1,213 116,580 $ 865 590,415 $ 462 Change in value of Series A Warrants — (655 ) — — — — De-recognition of Series B Warrant liability upon cashless exercise of warrants (485,202 shares issued) — — (102,300 ) (593 ) — — De-recognition of Series B Warrant liability upon expiration — — (14,280 ) — — — Change in value of Series B Warrants — — — (272 ) — — Change in value of Series C Warrants — — — — — (243 ) Balance at March 31, 2016 2,425,605 $ 558 — $ — 590,415 $ 219 |

Equity [Abstract] | |
Warrant Liabilities | Warrant Liabilities Warrants terms The Company has issued Series A Warrants, Series B Warrants and Series C Warrants (the “Warrants”). The Company’s Warrants contain standard anti-dilution provisions for stock dividends, stock splits, subdivisions, combinations and similar types of recapitalization events. They also contain a cashless exercise feature that provides for their net share settlement at the option of the holder in the event that there is no effective registration statement covering the continuous offer and sale of the warrants and underlying shares. The Company is required to comply with certain requirement to cause or maintain the effectiveness of a registration statement for the offer and sale of these securities. The Warrant contracts further provide for the payment of liquidated damages at an amount per month equal to 1% of the aggregate VWAP of the shares into which each Warrant is convertible into in the event that the Company is unable to maintain the effectiveness of a registration statement as described herein. The Company evaluated the registration payment arrangement stipulated in the terms of these securities and determined that it is probable that the Company will maintain an effective registration statement and has therefore not allocated any portion of the Company's cash or cash equivalents to the registration payment arrangement. The Warrants also contain a fundamental transactions provision that permits their settlement in cash at fair value at the option of the holder upon the occurrence of a change in control. Such change in control events include tender offers or hostile takeovers, which are not within the sole control of the Company as the issuer of these Warrants. Accordingly, the Warrants are considered to have a cash settlement feature that precludes their classification as equity instruments. Settlement at fair value upon the occurrence of a fundamental transaction would be computed using the Black Scholes Option Pricing Model. Accounting Treatment The Company accounts for the Warrants in accordance with the guidance in ASC 815 Derivatives and Hedging . As indicated above, the Company may be obligated to settle Warrants in cash in the case of a Fundamental Transaction. The Company classified the Warrants as liabilities at their fair value and will re-measure the warrants at each balance sheet date until they are exercised or expire. Any change in the fair value is recognized as other income (expense) in the Company’s statement of operations. Under ASC 815-40-35, the Company adopted a sequencing policy that reclassifies contracts, with the exception of stock options, from equity to assets or liabilities for those with the latest inception date first. Future issuance of securities will be evaluated as to reclassification as a liability under our sequencing policy of latest inception date first until either all of the Series B Warrants are settled or expire. The Series B Warrants expired on February 12, 2016. In accordance with the guidance under ASC 815-40-25, we have evaluated that we have a sufficient number of authorized and unissued shares as March 31, 2016, to settle all existing commitments. Series A Warrants The Company has issued 2,449,605 Series A Warrants to purchase shares of its Common Stock at an exercise price of $6.50 per share in connection with the unit offering offered in the Company's initial public offering ("IPO") described in Note 2. The Series A Warrants are exercisable at any time prior to the expiration of the five -year term on November 12, 2019. Upon the completion of the IPO, the Series A Warrants started trading on the NASDAQ under the symbol CAPNW. As the Series A Warrants are publicly traded, the Company uses the closing price on the measurement date to determine the fair value of these the Series A Warrants. Since their issuance, a total of 24,000 Series A Warrants have been exercised. As of March 31, 2016, the fair value of the 2,425,605 outstanding Series A Warrants was approximately $558 thousand , and the decrease of $655 thousand in fair value during the three months ended March 31, 2016 was recorded as other income in the statement of operations. Series B Warrants The Company issued 2,449,605 Series B Warrants to purchase shares of its Common Stock at an exercise price of $6.50 per share in connection with the Intial Public Offering. The unexercised Series B Warrants expired on February 12, 2016. The net decrease in carrying amount of the Series B Warrants for the three months ended March 31, 2016 was $865 thousand , of which $271 thousand was attributed to the change in fair value of the warrant liability during the three months ended March 31, 2016 and was recorded as other expense in the consolidated statement of operations. Factors contributing to the change in fair value of the Series B Warrants include the trading price of the Common Stock and term remaining to expiration of the Series B Warrants. Before the expiration date of February 12, 2016, certain holders of Series B warrants cashless exercised a total of 102,300 warrants resulting in the issuance of 485,202 shares of Common Stock and the derecognition of approximately $594 thousand , in Series B Warrant liability, respectively for the three months ended March 31, 2016, which was recorded as additional paid-in capital. Series C Warrants On March 5, 2015, the Company entered into separate agreements with certain Series B Warrant holders, who agreed to exercise their Series B Warrants to purchase an aggregate of 589,510 shares of the Company’s Common Stock at an exercise price of $6.50 per share, resulting in the de-recognition of $6.7 million of Series B Warrant liability and gross proceeds to the Company of approximately $3.8 million based on the exercise price of the Series B Warrants. In connection with this exercise of the Series B Warrants, the Company issued to each investor who exercised Series B Warrants, new Series C Warrants for the number of shares of the Company’s Common Stock underlying the Series B Warrants that were exercised. Each Series C Warrant is exercisable at $6.25 per share and will expire on March 5, 2020 . In April 2015, the Company issued a tender offer to the remaining holders of Series B Warrants to induce the holders to cash exercise the outstanding Series B Warrants in exchange for new Series C Warrants with an exercise price of $6.25 per share that expire on March 5, 2020 . The tender offer was extended to warrant holders under a registration statement filed with the SEC on Form S-4, which was declared effective on June 25, 2015 and expired on July 24, 2015 . During July 2015, certain Series B Warrant holder(s) tendered their Series B Warrants under the tender offer, which resulted in the issuance of 905 shares of Capnia Common Stock, the issuance of 905 Series C Warrants and proceeds to the Company of $5,882 . The new Series C Warrants are exercisable into 590,415 shares of the Company’s Common Stock. As of March 31, 2016, the fair value of the Series C Warrants was determined to be $219 thousand . The decline in the fair value of the Series C Warrants of $244 thousand in the three months ended March 31, 2016 was recorded as other income in the consolidated statement of operations. The Company has calculated the fair value of the Series C Warrants using a Black-Scholes pricing model, which requires the input of highly subjective assumptions including the expected stock price volatility. The Company used the following inputs: March 31, 2016 December 31, 2015 Volatility 90 % 90 % Expected Term (years) 3.92 4.17 Expected dividend yield — % — % Risk-free rate 1.03 % 1.76 % |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Facility Leases On July 1, 2015 the Company executed a new four year non-cancelable operating lease agreement for 8,171 square feet of office space for its headquarters facility. The lease agreement provides for monthly lease payments of $23,300 beginning in September of 2015, with increases in the following three years. An additional 5,265 square feet of office space became part of the new lease agreement on March 1, 2016. The Company leases office space under a non-cancelable operating lease agreement which was set to expire in May 2015. On February 2, 2015, the Company signed an amendment to its lease agreement, extending the lease through June 2018. The amendment provides for monthly lease payments of $22,000 beginning in June 2015, with increases in the following two years. The Company subleased this facility in January 2016 and ceased use of the facility in March 2016 (See Note 4). The Company also leases approximately 2,100 square feet of office space for its operations in Ivyland, Pennsylvania under a month-to-month lease. Rent expense was $184 thousand and $62 thousand during the three months ended March 31, 2016 and 2015, respectively. Contingencies In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In connection with the acquisition of the assets of NFG, the Company agreed to pay the former NFG shareholder an annual royalty payment for a period of 36 months. The agreement to pay the annual royalty resulted in the recognition of a contingent consideration, which is recognized at the inception of the transaction, and subsequent changes to estimate of the amounts of contingent consideration to be paid will be recognized as charges or credits in the statement of operations. The fair value of the contingent consideration is based on preliminary cash flow projections, growth in expected product sales and other assumptions. Based on the assumptions, the fair value of the royalty was determined to be $153 thousand at the date of acquisition and $172 thousand at March 31, 2016. |

Equity [Abstract] | |
Stockholders' Equity | Stockholders’ Equity Convertible Preferred Stock The Company is authorized to issue 40,000 shares of Series A Convertible Preferred Stock. On January 8, 2016 the Company issued an aggregate of 5,445 shares of Series A Convertible Preferred Stock under the Sabby Purchase Agreement. The Company has issued a total of 10,000 Series A Convertible Preferred Stock, with a par value of $0.001 and a stated value of $1,000 per share. The Series A Convertible Preferred Stock do not have an expiration date and are not redeemable. During the three months ended March 31, 2016, the holders of the Series A Convertible Preferred Stock converted 1,665 shares of Series A Convertible Preferred Stock resulting in the issuance of 900,000 shares of Common Stock. Stock Option Plan The Company has adopted the 1999 Incentive Stock Plan, the 2010 Equity Incentive Plan, and the 2014 Equity Incentive Plan (together, the "Plans"). The 1999 Incentive Stock Plan expired in 2009, and the 2010 Equity Incentive Plan has been closed to new issuances. Therefore, the Company may issue options to purchase shares of common stock to employees, directors, and consultants only under the 2014 Equity Incentive Plan. Options granted under the 2014 Plan may be incentive stock options (“ISOs”) or nonqualified stock options (“NSOs”). ISOs may be granted only to Company employees and directors. NSOs may be granted to employees, directors, advisors, and consultants. The Board of Directors has the authority to determine to whom options will be granted, the number of options, the term, and the exercise price. Options are to be granted at an exercise price not less than fair value for an ISO or 85% of fair value for an NSO. For individuals holding more than 10% of the voting rights of all classes of stock, the exercise price of an option will not be less than 110% of fair value. The vesting period is normally monthly over a period of 4 years from the vesting date. The contractual term of an option is no longer than five years for ISOs for which the grantee owns greater than 10% of the voting power of all classes of stock and no longer than ten years for all other options. The Company recognized stock-based compensation expense related to options granted to employees for the three months ended March 31, 2016 and 2015 of $136 thousand and $401 thousand , respectively. The compensation expense is allocated on a departmental basis, based on the classification of the option holder. No income tax benefits have been recognized in the statements of operations for stock-based compensation arrangements as of March 31, 2016 and March 31, 2015. Stock compensation expense (in thousands) was allocated between departments as follows: Three months ended March 31, 2016 2015 Research & Development $ 33 $ 50 Sales & Marketing (31 ) 20 General & Administrative 134 331 Total $ 136 $ 401 The fair value of each award granted was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions: Three Months Ended March 31, 2016 2015 Expected life (years) 6.0-6.1 5.5-6.1 Risk-free interest rate 1.5%-1.7% 1.5%-1.6% Volatility 66% - 67% 57% - 68% Dividend rate —% —% Expected volatility is based on volatilities of a group of public companies operating in the Company’s industry. The expected life of stock options represents the average of the contractual term of the options and the weighted-average vesting period, as permitted under the simplified method. The Company has elected to use the simplified method, as the Company does not have enough historical exercise experience to provide a reasonable basis upon which to estimate the expected term and the stock option grants are considered “plain vanilla” options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The following table summarizes stock option transactions issued under the Plans: Shares Available for Grant Number of Options Outstanding Weighted-Average Exercise Price per Share Weighted Average Remaining Contractual Term (in years) Balance at December 31, 2014 606,061 1,072,011 6.34 8.67 Additional shares authorized 270,764 Options granted (955,713 ) 955,713 3.08 Options exercised (83,848 ) 3.50 Options canceled/forfeited 85,037 (85,037 ) 5.03 Balance at December 31, 2015 6,149 1,858,839 4.82 8.75 Additional shares authorized 560,717 Options granted (538,500 ) 538,500 1.59 Options exercised — — Options canceled/forfeited 99,700 (99,700 ) 2.33 Balance at March 31, 2016 128,066 2,297,639 $ 4.09 8.77 Future stock-based compensation for unvested employee options granted and outstanding as of March 31, 2016 is approximately $1.8 million to be recognized over a remaining requisite service period of 3.2 years. The fair value of an equity award granted to a non-employee generally is determined in the same manner as an equity award granted to an employee. In most cases, the fair value of the equity securities granted is more reliably determinable than the fair value of the goods or services received. Stock-based compensation related to its grant of options to non-employees has not been material to date. 2014 Employee Stock Purchase Plan Our Board of Directors and stockholders have adopted the 2014 Employee Stock Purchase Plan, or the ESPP. The ESPP has become effective, and our Board of Directors will implement commencement of offers thereunder in its discretion. A total of 139,839 shares of our Common Stock has been made available for sale under the ESPP. In addition, our ESPP provides for annual increases in the number of shares available for issuance under the plan on the first day of each year beginning in the year following the initial date that our Board of Directors authorizes commencement, equal to the least of: • 1.0% of the outstanding shares of our Common Stock on the first day of such year; 279,680 shares; or • such amount as determined by our Board of Directors. As of March 31, 2016 there were no purchases by employees under this plan. Series D Warrants The Company has issued 2,810,811 Series D Warrants, with an exercise price of $2.46 and a term of five years expiring on October 15, 2020. The Company’s Series D Warrants contain standard anti-dilution provisions for stock dividends, stock splits, subdivisions, combinations and similar types of recapitalization events. They also contain a cashless exercise feature that provides for their net share settlement at the option of the holder in the event that there is no effective registration statement covering the continuous offer and sale of the warrants and underlying shares. The Company is required to comply with certain requirement to cause or maintain the effectiveness of a registration statement for the offer and sale of these securities. The Series D Warrant agreement further provides for the payment of liquidated damages at an amount per month equal to 1% of the aggregate VWAP of the shares into which each Series D Warrant is convertible into in the event that the Company is unable to maintain the effectiveness of a registration statement as described herein. The Company evaluated the registration payment arrangement stipulated in the terms of this securities agreement and determined that it is probable that the Company will maintain an effective registration statement and has therefore not allocated any portion of the proceeds to the registration payment arrangement. The Series D Warrant agreement specifically provides that under no circumstances will the Company be required to settle any Series D Warrant exercise for cash, whether by net settlement or otherwise. Accounting Treatment The Company accounts for the Series D Warrants in accordance with the guidance in ASC 815 Derivatives and Hedging . As indicated above, the Company is not required under any circumstance to settle any Series D Warrant exercise for cash. The Company has therefore classified the value of the Series D Warrants as permanent equity. Other Common Stock Warrants As of March 31, 2016, the Company had 480,147 Common Stock warrants outstanding from the 2010/2012 convertible notes, with an exercise price of $4.87 and a term of 10 years expiring in November 2024. The Company also has outstanding 9,259 Common Stock warrants issued in 2009, with an exercise price of $21.60 and a term of 10 years, expiring in January 2019 and 82,500 Common Stock warrants issued to the underwriter in our IPO, with an exercise price of $7.14 and a term of 10 years, expiring in November 2024. |

Earnings Per Share [Abstract] | |
Net loss per share | Net loss per share Basic net loss per share is computed by dividing net loss by the weighted-average number of Common Stock actually outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of Common Stock outstanding and dilutive potential Common Stock that would be issued upon the exercise of Common Stock warrants and options. For the three months ended March 31, 2016 and 2015, the effect of issuing the potential common stock is anti-dilutive due to the net losses in those periods and the number of shares used to compute basic and diluted earnings per share are the same in each of those periods. The following potentially dilutive securities outstanding have been excluded from the computations of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in Common Stock equivalent shares): As of March 31, 2016 2015 Convertible preferred stock 4,505,405 — Warrants issued to 2010/2012 convertible note holders to purchase common stock 480,147 480,147 Options to purchase common stock 2,297,639 1,458,964 Warrants issued in 2009 to purchase common stock 9,259 9,259 Warrants issued to underwriter to purchase common stock 82,500 82,500 Series A Warrants to purchase common stock 2,425,605 2,425,605 Series B Warrants to purchase common stock — 1,778,275 Series C Warrants to purchase common stock 590,415 589,510 Series D Warrants to purchase common stock 2,810,812 — |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly the Company's financial position as of March 31, 2016 and results of its operations and cash flows for the three months ended March 31, 2016 and 2015. The interim results are not necessarily indicative of the results for any future interim period or for the entire year. Certain prior period amounts have been reclassified to conform to current period presentation. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2015 included in the Company's Annual Report on Form 10-K. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of expenses in the financial statements and accompanying notes. Actual results could differ from those estimates. Key estimates included in the financial statements include the valuation of deferred income tax assets, liability and equity instruments, stock-based compensation, acquired intangibles, contingent earn-out consideration, and allowances for accounts receivable and inventory. |
Inventory | Inventory is stated at the lower of cost or market under the first-in, first-out (FIFO) method. |
Intangible Assets | Intangible Assets Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which range in term from 5 to 12 years. The useful life of the intangible asset is evaluated each reporting period to determine whether events and circumstances warrant a revision to the remaining useful life. |
Goodwill | Goodwill The Company tests its goodwill for impairment annually, or whenever events or changes in circumstances indicate an impairment may have occurred, by comparing its reporting unit’s carrying value to its implied fair value. Impairment may result from, among other things, deterioration in the performance of the acquired business, adverse market conditions, adverse changes in applicable laws or regulations and a variety of other circumstances. If the Company determines that an impairment has occurred, it is required to record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. In evaluating the recoverability of the carrying value of goodwill the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the acquired assets. Changes in strategy or market conditions could significantly impact those judgments in the future and require an adjustment to the recorded balances. There was no impairment of goodwill for the three months ended March 31, 2016. Such goodwill is not deductible for tax purposes and represents the value placed on entering new markets and expanding market share. |
Common Stock Purchase Warrants and Other Derivative Financial Instruments | Common Stock Purchase Warrants and Other Derivative Financial Instruments The Company classifies Common Stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that certain freestanding derivatives, which principally consist of Series A, Series B, and Series C Warrants to purchase Common Stock, do not satisfy the criteria for classification as equity instruments due to the existence of certain cash settlement features that are not within the sole control of the Company or variable settlement provision that cause them to not be indexed to the Company’s own stock. Due to certain provisions contained in the Series B Warrant agreement that provides for the Company potentially issuing an unlimited number of shares upon exercise, the Company had adopted a sequencing policy that reclassified contracts, with the exception of stock options, from equity to assets or liabilities for those with the latest inception date first. The Company had evaluated the issuance of securities as to reclassification as a liability under this sequencing policy through February 12, 2016, the date that the Series B Warrants expired. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements There have been no new accounting pronouncements or changes to accounting pronouncements during the three months ended March 31, 2016 as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 that are of significance or potential significance to the Company. |
