Significant Accounting Policies [Text Block]	'
	Note 2 — Summary of Significant Accounting Policies
	Basis of Presentation
	On November 21, 2013, the Company effected a 1-for-2.381 reverse stock split of its issued common stock. All applicable share date, per share amounts and related information in the financial statements and notes thereto have been adjusted retroactively to give effect to the 1-for-2.381 reverse stock split. Certain prior year amounts have been reclassified to conform to the current year presentation. These changes had no impact on total revenue, loss from operations or net loss.
	Use of Estimates
	The preparation of financial statements in conformity with US GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
	Accounts Receivable
	Trade accounts receivable are stated net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral from its customers or interest on past due amounts. Management estimates the allowance for doubtful accounts based on review and analysis of specific customer balances that may not be collectible and how recently payments have been received. Accounts are considered for write-off when they become past due and when it is determined that the probability of collection is remote. There was no allowance for doubtful accounts at December 31, 2013 and 2012.
	Inventories
	Inventories are stated at the lower of cost (first in, first out method) or market value. Inventory quantities on hand are reviewed regularly and a write-down for excess and obsolete inventory is recorded based primarily on an estimated forecast of product demand, market conditions and anticipated production requirements in the near future. There was no reserve for excess and obsolete inventory at December 31, 2013 and 2012.
	Property and Equipment
	Property and equipment are stated at historical cost less accumulated depreciation and amortization. Major additions and improvements are capitalized while maintenance and repairs that do not improve or extend the useful life of the respective asset are expensed. Depreciation and amortization of property and equipment is computed using the straight-line method over the estimated useful lives. Leasehold improvements are amortized over the shorter of the life of the asset or the related leases. Estimated useful lives of the principal classes of assets are as follows:
	Leasehold improvements	2 years
	Machinery and equipment	5 years
	Furniture, fixtures and computers	3 – 5 years
	Patents
	Patents are recorded at cost. The Company capitalizes third party legal costs and filing fees associated with obtaining patents on its new discoveries. Once the patents have been issued, the Company amortizes these costs over the shorter of the legal life of the patent or its estimated economic life, generally 20 years, using the straight-line method.
	Impairment of Long-Lived Assets
	The long-lived assets held and used by the Company are reviewed for impairment no less frequently than annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the event that facts and circumstances indicate that the cost of any long-lived assets may be impaired, an evaluation of recoverability is performed. Management has determined that there was no impairment in the value of long-lived assets during the years ended December 31, 2013 and 2012.
	Fair Value of Financial Instruments
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable and accounts payable. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short maturities of these instruments. The Company did not identify any other non-recurring assets and liabilities that are required to be presented in the balance sheets at fair value.
	Convertible Promissory Notes and Warrants
	The warrants and embedded conversion feature of convertible promissory notes are classified as equity under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815-40 “Derivatives and Hedging — Contracts in Entity’s Own Equity”. The Company allocates the proceeds of the convertible promissory notes between convertible promissory notes and the financial instruments related to warrants associated with convertible promissory notes based on their relative fair values at the commitment date. The fair value of the financial instruments related to warrants associated with convertible promissory notes is determined utilizing the Black-Scholes option pricing model and the respective allocated proceeds to the warrants is recorded in additional paid-in capital. The Company utilized the Black-Scholes option valuation model using the same valuation assumptions as described herein for Stock Based Compensation. The embedded beneficial conversion feature associated with convertible promissory notes is recognized and measured by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital in accordance with ASC Topic 470-20 “Debt — Debt with Conversion and Other Options”.
	The portion of debt discount resulting from the allocation of proceeds to the financial instruments related to warrants associated with convertible promissory notes is being amortized over the life of the convertible promissory notes. For the portion of debt discount resulting from the allocation of proceeds to the beneficial conversion feature, it is amortized over the term of the notes from the respective dates of issuance. The Company wrote-off the remaining unamortized debt discount upon the conversion of the convertible promissory notes to common stock immediately upon completion of the Company’s initial public offering.
	Revenue Recognition
	Revenue from product sales is recognized when the risks of loss and title pass to the customer, as specified in (1) the respective sales agreements and (2) other revenue recognition criteria as prescribed by Staff Accounting Bulletin (“SAB”) No. 101 (SAB 101), “Revenue Recognition in Financial Statements,” as amended by SAB No. 104, “Revenue Recognition”. The Company generally sells its products FOB shipping and recognizes revenue when products are shipped. Revenue from service contracts is recognized using the completed-performance or proportional-performance method depending on the terms of the service agreement. When there are acceptance provisions based on customer-specified subjective criteria, the completed-performance method is used. For contracts where the services performed in the last series of acts is very significant, in relation to the entire contract, performance is not deemed to have occurred until the final act is completed. Once customer acceptance has been received, or the last significant act is performed, revenue is recognized. The Company uses the proportional-performance method when a service contract specifies a number of acts to be performed and the Company has the ability to determine the pattern and related value in which service is provided to the customer.
	The Company receives payments from government entities in the form of government grants. Government grants are agreements that generally provide the Company with cost reimbursement for certain type of research and development activities over a contractually defined period. Revenues from government grants are recognized in the period during which the Company incurs the related costs, provided that the Company has incurred the cost in accordance with the specifications and work plans determined between the Company and the government entity. Costs incurred related to the grants are recorded as grant research and development costs. Government grants amounted to $1,374,956 and $707,357 for the years ended December 31, 2013 and 2012, respectively. At December 31, 2013 and 2012, grants receivable amounted to $211,063 and $348,647, respectively, and were included in accounts receivable.
	Royalty income is recognized as earned based on the terms of the contractual agreements and has no direct costs.
	Product Warranties
	The Company generally provides a ten year manufacturer’s warranty covering product defects. Accruals for product warranties are estimated based upon historical warranty experience and are recorded in cost of sales at the time revenue is recognized in order to match revenues with related expenses. The Company assesses the adequacy of its warranty liability quarterly and adjusts the reserve, included in accrued expenses, as necessary.
	Research and Development
	Grant research and development are costs incurred solely related to grant revenues, and are classified as a line item under cost of revenues.
	Other research and development costs are presented as a line item under operating expenses and are expensed as incurred. Total research and development costs incurred during the years ended December 31, 2013 and 2012 amounted to $2,643,096 and $1,760,111, respectively, of which $1,430,798 and $709,954, respectively, was included in cost of revenues.
	Income Taxes
	The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. At December 31, 2013 and 2012, the Company has established a full reserve against all deferred tax assets.
	Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.
	Net Loss Per Share
	The Company applies FASB ASC 260, “Earnings per Share.” Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include additional common shares available upon exercise of stock options and warrants using the treasury stock method, except for periods for which no common share equivalents are included because their effect would be anti-dilutive.
	Stock Based Compensation
	The Company applies FASB ASC 718, “Stock Compensation,” when recording stock based compensation. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option valuation model. The assumptions used in the Black-Scholes valuation model are as follows:
	Grant Price — The grant price of the issuances are determined based on the estimated fair value of the shares at the date of grant.
	Risk-free interest rate — The risk free interest rate for periods within the contractual life of the option is based on the U.S. treasury yield in effect at the time of grant.
	Expected lives — As permitted by SAB 107, due to the Company's insufficient history of option activity, the management utilizes the simplified approach to estimate the options expected term, which represents the period of time that options granted are expected to be outstanding.
	Expected volatility — is determined based on management's estimate or historical volatilities of comparable companies.
	Expected dividend yield — is based on current yield at the grant date or the average dividend yield over the historical period. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.
	The Company accounts for stock issued to non-employees in accordance with the provisions of FASB ASC 505-50 “Equity Based Payments to Non-Employees.” FASB ASC 505-50 states that equity instruments that are issued in exchange for the receipt of goods or services should be measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. The measurement date occurs as of the earlier of (a) the date at which a performance commitment is reached or (b) absent a performance commitment, the date at which the performance necessary to earn the equity instruments is complete (that is, the vesting date).
	Presentation of Sales Taxes
	Certain states impose a sales tax on the Company’s sales to nonexempt customers. The Company collects that sales tax from customers and remits the entire amount to the states. The Company’s accounting policy is to exclude the tax collected and remitted to the states from revenues and cost of revenues.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable and accounts payable. The Company maintains its cash with a major financial institution located in the United States. Balances are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company maintains balances in excess of federally insured limits.
	The Company encounters a certain amount of risk as a result of a concentration of revenue from a few significant customers. Credit is extended to customers based on an evaluation of their financial condition. The Company generally does not require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers and records an allowance for potential bad debts based on available information. The Company had revenue from a government entity that accounted for 65% of net revenue for the year ended December 31, 2013 and two customers, including a government entity, that accounted for 75% of net revenue for the year ended December 31, 2012. The Company had an accounts receivable balance from a government entity that accounted for 84% and 72% of total accounts receivable at December 31, 2013 and 2012, respectively.
	Recent Accounting Pronouncements
	Management does not believe that any recently issued, but not yet effective, accounting standards, if adopted, will have a material effect on the financial statements.

Under the Agreement, the Company received an initial award totaling $250,000 during the year ended December 31, 2010 and received an additional award totaling $750,000 during the year ended December 31, 2011 (collectively, the “Promissory Note”). The proceeds from the award had to be used to expedite commercialization intended to increase high-quality jobs in Texas through expenditures on working capital or development or acquisition of capital assets used to produce income and in meeting the Company’s goal of introducing a 30KW solar inverter to the market. The Company was also required to meet certain milestones by specific dates, use Texas-based suppliers and establish a substantial percentage of its commercialization and manufacturing activities in Texas. The awards were collateralized by all owned or acquired assets of the Company. The ETF, in a subordination agreement dated August 30, 2012, agreed to subordinate the Promissory Note to secured convertible promissory notes to be issued by the Company of up to $5,000,000.

	Note 11 — Stock Option Plan
	On May 17, 2013, the Company adopted the 2013 Equity Incentive Plan (the “Plan”) and reserved 487,932 shares of common stock for issuance under the Plan, including stock options, stock awards and stock bonuses. The maximum number of shares that may be granted under the Plan will be increased effective the first day of each of the Company’s fiscal quarters provided that the number of shares that may be granted under the Plan does not exceed 839,983 shares. The Plan is administered by the Compensation Committee of the Company’s board of directors. The persons eligible to participate in the Plan are employees, non-employee members of the board of directors, consultants and other independent advisors who provide services to the Company. Options issued under the Plan may have a term of up to ten years and may have variable vesting.
	On July 19, 2013, the Company granted 346,813 stock options to various employees to purchase shares of common stock at an exercise price of $5.00 per share. The options vest in equal installments on December 31, 2013, 2014 and 2015. During November and December 2013, the Company granted 40,500 stock options to newly hired employees and 69,859 stock options in connection with separation agreements. The exercise price of the stock options issued to new employees was the closing price of the Company’s stock on the date of grant and the options vest in equal annual installments over 4 years. The exercise price and vesting term of the separation options was set in accordance with the separation agreements. The options granted in 2013 were valued at $1,508,832 using the Black-Scholes option pricing model.
	Awards Granted Outside the Plan
	During the year ended December 31, 2012, the Company granted 18,965 stock options to purchase shares of common stock at an exercise price of $6.328 to an executive employee. The options were scheduled to vest over a period of 4 years commencing from the date of grant. During 2013, these options were forfeited upon termination of the employee. The options were valued at approximately $85,000 using the Black-Scholes option pricing model. Approximately $15,943 and $12,400, respectively, relating to these options was charged to expense during the years ended December 31, 2013 and 2012.
	As permitted by SAB 107, due to the Company’s insufficient history of option activity, management utilizes the simplified approach to estimate the expected term of stock options, which represents the period of time that options granted are expected to be outstanding. The risk free interest rate for periods within the contractual life of the option is based on the U.S. treasury yield in effect at the time of grant. The volatility is determined based on management’s estimate or historical volatilities of comparable companies. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.
	The assumptions used in the Black-Scholes model are as follows:
		For the year ended December 31,
		2013	2012
	Risk-free interest rate	1.46 to 1.86%	1.41%
	Expected dividend yield	0%	0%

	Note 13 — Income Taxes
	Income taxes are disproportionate to income due to net operating loss carryforwards, which are fully reserved. As of December 31, 2013, the Company has federal net operating loss carryforwards of approximately $8,966,000 which will begin to expire in 2031. Management has concluded that it is more likely than not that the Company will not have sufficient foreseeable taxable income within the carryforward period permitted by current law to allow for the utilization of certain of the deductible amounts generating the deferred tax assets; therefore, a full valuation allowance has been established to reduce the net deferred tax assets to zero at December 31, 2013 and 2012.
	The following is a summary of the significant components of the Company’s net deferred income tax assets and liabilities as of December 31, 2013 and 2012:
		Year ended December 31,

	The Company has applied the provisions of FASB ASC 740, “Income Tax” which clarifies the accounting for uncertainty in tax positions. FASB ASC 740 requires the recognition of the impact of a tax position in the financial statements if that position is more likely than not of being sustained on a tax return upon examination by the relevant taxing authority, based on the technical merits of the position. At December 31, 2013 and 2012, the Company had no unrecognized tax benefits.
	The Company recognizes interest and penalties related to income tax matters in interest expense and operating expenses, respectively. As of December 31, 2013 and 2012, the Company has no accrued interest and penalties related to uncertain tax positions.
	The Company is subject to tax in the United States (“U.S.”) and files tax returns in the U.S. federal and state jurisdictions. The Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years before 2009. The Company currently is not under examination by any tax authority.
	The reconciliation between the statutory income tax rate and the effective tax rate is as follows:

	The Company leases its facility in Spicewood, Texas under a non-cancelable operating lease expiring on May 31, 2014. Rent expense incurred for the years ended December 31, 2013 and 2012 amounted to $37,930 and $34,932, respectively.
	Employment Agreement
	The Company has entered into employment agreements with executive management personnel that provide for severance payments upon termination without cause. Consequently, if the Company had released executive management personnel without cause or due to a change in control, as defined in the employment agreements, the severance expense due would be a minimum six months of salary of approximately $312,000, or, for two members of executive management, the amount of compensation for the remaining term of their employment contract, whichever is higher, plus any pro-rated bonuses and vacation days earned but unused as of the date of termination.
	The following table summarizes the Company’s minimum obligation in the event of no early termination under the employment agreements:
	Year	Amount
	2014	$	423,000
	2015		149,000
		$	572,000
	Termination of Employment Agreement
	Effective October 25, 2013, the employment agreement for one member of executive management was terminated. The related separation agreement included severance of $87,500, accrued but unpaid wages of $58,835 and paid time-off of $9,019. These amounts were paid in November 2013. The separation agreement also includes the grant of an option to purchase 36,116 shares of common stock which may be exercised for a period of 12 months following the first anniversary of the consummation of the Company’s initial public offering. Of the 36,116 shares of common stock covered by the option agreement, 29,399 may be purchased at a per share price of $5.00 and 6,717 may be purchased at a per share price of $6.3276. Options to purchase 81,964 shares of common stock previously granted to the executive were forfeited either at the time of separation or at the time his separation agreement became irrevocable with both events occurring in the fourth quarter of 2013. The option grant was treated as a modification and the Company recorded a charge of $70,634 for this modification.

	Employment Agreement
	On January 8, 2014, the Company entered into an employment agreement with its Chief Executive Officer. The employment agreement has a term of three years. The agreement provides for severance payments upon termination without cause. Consequently, if the Company releases the executive without cause or due to a change in control, as defined in the employment agreement, the severance due would be a minimum one year’s salary of $300,000, plus any pro-rated bonus and vacations days earned but unused. The executive will be entitled to continue to participate in employee benefit plans, at the Company’s sole expense, for a period of one year following the termination of his employment.
	The Company issued a non-qualified stock option to the executive (the “Inducement Option”) to purchase 250,000 shares of the Company’s common stock at a per share exercise price of $7.14, equal to the closing price of the Company’s common stock on January 8, 2014, the date of grant. The right to purchase the shares subject to the Inducement Option will vest in equal increments over a period of four years, beginning on December 31, 2014 and continuing thereafter on each subsequent December 31st through the end of the vesting period. The Inducement Option has a term of 10 years and will not be subject to the terms of the Company’s 2013 Equity Incentive Plan.
	Lease Agreement
	On March 24, 2014, the Company entered into a lease for 14,782 square feet of office and laboratory space located at 4120 Freidrich Lane, Suite 100, Austin, Texas 78744. The triple net lease has a term of 48 months and the Company expects the commencement date of the lease to be approximately June 1, 2014. The annual base rent in the first year of the lease is $154,324 and increases by $3,548 in each succeeding year of the lease.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Accounting, Policy [Policy Text Block]	'
	Basis of Presentation
	On November 21, 2013, the Company effected a 1-for-2.381 reverse stock split of its issued common stock. All applicable share date, per share amounts and related information in the financial statements and notes thereto have been adjusted retroactively to give effect to the 1-for-2.381 reverse stock split. Certain prior year amounts have been reclassified to conform to the current year presentation. These changes had no impact on total revenue, loss from operations or net loss.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	The preparation of financial statements in conformity with US GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	'
	Accounts Receivable
	Trade accounts receivable are stated net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral from its customers or interest on past due amounts. Management estimates the allowance for doubtful accounts based on review and analysis of specific customer balances that may not be collectible and how recently payments have been received. Accounts are considered for write-off when they become past due and when it is determined that the probability of collection is remote. There was no allowance for doubtful accounts at December 31, 2013 and 2012.
Inventory, Policy [Policy Text Block]	'
	Inventories
	Inventories are stated at the lower of cost (first in, first out method) or market value. Inventory quantities on hand are reviewed regularly and a write-down for excess and obsolete inventory is recorded based primarily on an estimated forecast of product demand, market conditions and anticipated production requirements in the near future. There was no reserve for excess and obsolete inventory at December 31, 2013 and 2012.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Property and Equipment
	Property and equipment are stated at historical cost less accumulated depreciation and amortization. Major additions and improvements are capitalized while maintenance and repairs that do not improve or extend the useful life of the respective asset are expensed. Depreciation and amortization of property and equipment is computed using the straight-line method over the estimated useful lives. Leasehold improvements are amortized over the shorter of the life of the asset or the related leases. Estimated useful lives of the principal classes of assets are as follows:
	Leasehold improvements	2 years
	Machinery and equipment	5 years
	Furniture, fixtures and computers	3 – 5 years
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	'
	Patents
	Patents are recorded at cost. The Company capitalizes third party legal costs and filing fees associated with obtaining patents on its new discoveries. Once the patents have been issued, the Company amortizes these costs over the shorter of the legal life of the patent or its estimated economic life, generally 20 years, using the straight-line method.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	'
	Impairment of Long-Lived Assets
	The long-lived assets held and used by the Company are reviewed for impairment no less frequently than annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the event that facts and circumstances indicate that the cost of any long-lived assets may be impaired, an evaluation of recoverability is performed. Management has determined that there was no impairment in the value of long-lived assets during the years ended December 31, 2013 and 2012.
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Fair Value of Financial Instruments
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable and accounts payable. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short maturities of these instruments. The Company did not identify any other non-recurring assets and liabilities that are required to be presented in the balance sheets at fair value.
Debt, Policy [Policy Text Block]	'
	Convertible Promissory Notes and Warrants
	The warrants and embedded conversion feature of convertible promissory notes are classified as equity under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815-40 “Derivatives and Hedging — Contracts in Entity’s Own Equity”. The Company allocates the proceeds of the convertible promissory notes between convertible promissory notes and the financial instruments related to warrants associated with convertible promissory notes based on their relative fair values at the commitment date. The fair value of the financial instruments related to warrants associated with convertible promissory notes is determined utilizing the Black-Scholes option pricing model and the respective allocated proceeds to the warrants is recorded in additional paid-in capital. The Company utilized the Black-Scholes option valuation model using the same valuation assumptions as described herein for Stock Based Compensation. The embedded beneficial conversion feature associated with convertible promissory notes is recognized and measured by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital in accordance with ASC Topic 470-20 “Debt — Debt with Conversion and Other Options”.
	The portion of debt discount resulting from the allocation of proceeds to the financial instruments related to warrants associated with convertible promissory notes is being amortized over the life of the convertible promissory notes. For the portion of debt discount resulting from the allocation of proceeds to the beneficial conversion feature, it is amortized over the term of the notes from the respective dates of issuance. The Company wrote-off the remaining unamortized debt discount upon the conversion of the convertible promissory notes to common stock immediately upon completion of the Company’s initial public offering.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition
	Revenue from product sales is recognized when the risks of loss and title pass to the customer, as specified in (1) the respective sales agreements and (2) other revenue recognition criteria as prescribed by Staff Accounting Bulletin (“SAB”) No. 101 (SAB 101), “Revenue Recognition in Financial Statements,” as amended by SAB No. 104, “Revenue Recognition”. The Company generally sells its products FOB shipping and recognizes revenue when products are shipped. Revenue from service contracts is recognized using the completed-performance or proportional-performance method depending on the terms of the service agreement. When there are acceptance provisions based on customer-specified subjective criteria, the completed-performance method is used. For contracts where the services performed in the last series of acts is very significant, in relation to the entire contract, performance is not deemed to have occurred until the final act is completed. Once customer acceptance has been received, or the last significant act is performed, revenue is recognized. The Company uses the proportional-performance method when a service contract specifies a number of acts to be performed and the Company has the ability to determine the pattern and related value in which service is provided to the customer.
	The Company receives payments from government entities in the form of government grants. Government grants are agreements that generally provide the Company with cost reimbursement for certain type of research and development activities over a contractually defined period. Revenues from government grants are recognized in the period during which the Company incurs the related costs, provided that the Company has incurred the cost in accordance with the specifications and work plans determined between the Company and the government entity. Costs incurred related to the grants are recorded as grant research and development costs. Government grants amounted to $1,374,956 and $707,357 for the years ended December 31, 2013 and 2012, respectively. At December 31, 2013 and 2012, grants receivable amounted to $211,063 and $348,647, respectively, and were included in accounts receivable.
	Royalty income is recognized as earned based on the terms of the contractual agreements and has no direct costs.
Standard Product Warranty, Policy [Policy Text Block]	'
	Product Warranties
	The Company generally provides a ten year manufacturer’s warranty covering product defects. Accruals for product warranties are estimated based upon historical warranty experience and are recorded in cost of sales at the time revenue is recognized in order to match revenues with related expenses. The Company assesses the adequacy of its warranty liability quarterly and adjusts the reserve, included in accrued expenses, as necessary.
Research and Development Expense, Policy [Policy Text Block]	'
	Research and Development
	Grant research and development are costs incurred solely related to grant revenues, and are classified as a line item under cost of revenues.
	Other research and development costs are presented as a line item under operating expenses and are expensed as incurred. Total research and development costs incurred during the years ended December 31, 2013 and 2012 amounted to $2,643,096 and $1,760,111, respectively, of which $1,430,798 and $709,954, respectively, was included in cost of revenues.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. At December 31, 2013 and 2012, the Company has established a full reserve against all deferred tax assets.
	Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.
Earnings Per Share, Policy [Policy Text Block]	'
	Net Loss Per Share
	The Company applies FASB ASC 260, “Earnings per Share.” Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include additional common shares available upon exercise of stock options and warrants using the treasury stock method, except for periods for which no common share equivalents are included because their effect would be anti-dilutive.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock Based Compensation
	The Company applies FASB ASC 718, “Stock Compensation,” when recording stock based compensation. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option valuation model. The assumptions used in the Black-Scholes valuation model are as follows:
	Grant Price — The grant price of the issuances are determined based on the estimated fair value of the shares at the date of grant.
	Risk-free interest rate — The risk free interest rate for periods within the contractual life of the option is based on the U.S. treasury yield in effect at the time of grant.
	Expected lives — As permitted by SAB 107, due to the Company's insufficient history of option activity, the management utilizes the simplified approach to estimate the options expected term, which represents the period of time that options granted are expected to be outstanding.
	Expected volatility — is determined based on management's estimate or historical volatilities of comparable companies.
	Expected dividend yield — is based on current yield at the grant date or the average dividend yield over the historical period. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.
	The Company accounts for stock issued to non-employees in accordance with the provisions of FASB ASC 505-50 “Equity Based Payments to Non-Employees.” FASB ASC 505-50 states that equity instruments that are issued in exchange for the receipt of goods or services should be measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. The measurement date occurs as of the earlier of (a) the date at which a performance commitment is reached or (b) absent a performance commitment, the date at which the performance necessary to earn the equity instruments is complete (that is, the vesting date).
Presentation of Sales Taxes Policy [Policy Text Block]	'
	Presentation of Sales Taxes
	Certain states impose a sales tax on the Company’s sales to nonexempt customers. The Company collects that sales tax from customers and remits the entire amount to the states. The Company’s accounting policy is to exclude the tax collected and remitted to the states from revenues and cost of revenues.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable and accounts payable. The Company maintains its cash with a major financial institution located in the United States. Balances are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company maintains balances in excess of federally insured limits.
	The Company encounters a certain amount of risk as a result of a concentration of revenue from a few significant customers. Credit is extended to customers based on an evaluation of their financial condition. The Company generally does not require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers and records an allowance for potential bad debts based on available information. The Company had revenue from a government entity that accounted for 65% of net revenue for the year ended December 31, 2013 and two customers, including a government entity, that accounted for 75% of net revenue for the year ended December 31, 2012. The Company had an accounts receivable balance from a government entity that accounted for 84% and 72% of total accounts receivable at December 31, 2013 and 2012, respectively.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements
	Management does not believe that any recently issued, but not yet effective, accounting standards, if adopted, will have a material effect on the financial statements.
