Nature of the Business and Basis of Presentation [Abstract]
Nature of the Business and Basis of Presentation	1. Nature of the Business and Basis of Presentation SANUWAVE Health, Inc. and Subsidiaries (“SANUWAVE” or the “Company”) is focused on the research, development, and commercialization of its patented noninvasive and biological response activating medical systems for the repair and regeneration of skin, musculoskeletal tissue, and vascular structures. The Company’s lead regenerative product in the United States is the dermaPACE® device used for treating diabetic foot ulcers. Through the Company’s acquisition, on August 6, 2020, of the UltraMIST® assets from Celularity, Inc. (“Celularity”), SANUWAVE now combines two highly complementary and market-cleared energy transfer technologies and two human tissue biologic products, which creates a platform of scale with an end-to-end product offering in the advanced wound care market. Basis of Presentation – The accompanying unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8-03 of Regulation S-X. Accordingly, these Condensed Consolidated Financial Statements do not include all the information and disclosures required by U.S. GAAP for comprehensive financial statements. The financial information as of June 30 and for the three and six month ended June 30 and 2020 is unaudited; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2021. The Condensed Consolidated Balance Sheet at December 31, 2020 has been derived from the audited Consolidated Financial Statements at that date but does not include all of the information and disclosures required by U.S. GAAP for comprehensive financial statements. These financial statements should be read in conjunction with the Company’s December 31, 2020 Annual Report on Form 10-K filed with the SEC on October 21, 2021 (the “2020 Annual Report”).

Going Concern

Going Concern	6 Months Ended

Going Concern [Abstract]
Going Concern	2. Going Concern Our recurring losses from operations and dependency upon future issuances of equity or other financing to fund ongoing operations have raised substantial doubt as to our ability to continue as a going concern. We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so, and/or the terms of any financings may not be advantageous to us. The continuation of our business is dependent upon raising additional capital. We expect to devote substantial resources for the commercialization of the dermaPACE system and intend to continue to research and develop the non-medical uses of the PACE technology, both of which will require additional capital resources. The operating losses and the events of default on the Company’s notes payable indicate substantial doubt about the Company’s ability to continue as a going concern for a period of at least twelve months from the filing of this Quarterly Report on Form 10-Q. The continuation of our business is dependent upon raising additional capital to fund operations. Management’s plans are to obtain additional capital in 2022 through investments by strategic partners for market opportunities, which may include strategic partnerships or licensing arrangements, or raise capital through the conversion of outstanding warrants, issuance of common or preferred stock, securities convertible into common stock, or secured or unsecured debt. These possibilities, to the extent available, may be on terms that result in significant dilution to our existing shareholders. In addition, there can be no assurances that our plans to obtain additional capital will be successful on the terms or timeline we expect, or at all. Although no assurances can be given, management believes that potential additional issuances of equity or other potential financing transactions as discussed above should provide the necessary funding for us. If these efforts are unsuccessful, we may be required to significantly curtail or discontinue operations or, if available, obtain funds through financing transactions with unfavorable terms. The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the Condensed Consolidated Financial Statements do not necessarily purport to represent realizable or settlement values. The Condensed Consolidated Financial Statements do not include any adjustment that might result from the outcome of this uncertainty. Our Condensed Consolidated Financial Statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary should we be unable to continue as a going concern.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Significant accounting policies followed by the Company are summarized below and should be read in conjunction with those described in Note 3 to the Consolidated Financial Statements in our 2020 Annual Report. Estimates Significant estimates include the recording of allowances for doubtful accounts, the net realizable value of inventory, useful lives of long-lived assets, fair value of goodwill and other intangible assets, the determination of the valuation allowances for deferred taxes and the estimated fair value of embedded derivatives, including warrants and embedded conversion options on convertible debt issuances. Goodwill and Other Intangible Assets – Intangibles-Goodwill and Other Fair value of financial instruments - The carrying values of accounts payable, and other short-term obligations approximate their fair values, because of the short-term maturities of these instruments. The Company utilizes the guidance of ASC Topic 820-10, Fair Value Measurements (“ASC 820-10”), which defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. The framework that is set forth in this standard is applicable to the fair value measurements where it is permitted or required under other accounting pronouncements. The ASC 820-10 hierarchy ranks the quality and reliability of inputs, or assumptions, used in the determination of fair value and requires financial assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) in active markets for identical assets and liabilities; • Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and • Level 3 - Unobservable inputs that are not corroborated by market data, therefore requiring the Company to develop its own assumptions. The Company recognizes all derivatives on the Condensed Consolidated Balance Sheet at fair value. Each of the pricing models includes the use of unobservable inputs such as the expected term, anticipated volatility and risk-free interest rate, and therefore, is classified within Level 3 of the fair value hierarchy. Recent Accounting Pronouncements – Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity In May 2021, the FASB issued ASU 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). In December 2019, the FASB issued ASU 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment. The amendments in ASU 2017-04 modified the testing that an entity should perform for its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. This amendment is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2017-04 effective January 1, 2021. The adoption of this guidance did not impact our results of operations or financial position.

Loss per Share

Loss per Share [Abstract]
Loss per Share	4. Loss per Share The net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares outstanding for the three and six months ended June 30, 2021 and 2020. In accordance with ASC Topic 260-10-45-13, Earnings Per Share Accordingly, warrants issued with a $0.01 per share exercise price, are included in weighted average shares outstanding as follows: Three Months Ended Six Months Ended June 30, 2021 June 30, 2020 June 30, 2021 June 30, 2020 Weighted average shares outstanding Common shares 481,619,621 299,497,960 481,619,621 297,856,870 Common shares issuable assuming exercise of nominally priced warrants 36,691,160 - 36,780,387 - Weighted average shares outstanding 518,310,781 299,497,960 518,400,008 297,856,870 Diluted net loss per share would be computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding. To the extent that securities are “anti-dilutive,” they are excluded from the calculation of diluted net loss per share. As a result of the net loss for the three and six months ended June 30, 2021 and 2020, all potentially dilutive shares were anti-dilutive and therefore excluded from the computation of diluted net loss per share. Anti-dilutive equity securities consist of the following at June 30, 2021 and 2020, respectively (in thousands): 2021 2020 Common stock options 31,760 34,169 Common stock purchase warrants 150,202 9,374 Convertible notes payable 74,155 5,227 Short-term notes payable - 2,250 Convertible preferred stock - 17,500 256,117 68,520

Accounts Receivable Factoring	9. Accounts Receivable Factoring On June 17, 2021, the Company entered into a factoring agreement with Goodman Capital Finance (“Goodman”), an unrelated third party, pursuant to which the Company may sell certain of its accounts receivable to Goodman for 86.25% of the value of the receivable. Advances available under the facility are capped at the lesser of $3.0 million or a formula amount, as defined in the agreement. Interest on advances is assessed at a fixed amount upon funding, which is equivalent to an annualized rate of 15.0% for the first 30 days, and daily thereafter at an annualized rate of 14.4%. The agreement’s term is one month and automatically renews for additional one-month periods, unless either party provides 30 days’ notice of termination. The accounts receivable are sold with recourse back to the Company, which means that the Company bears the risk of non-payment by the account debtor. As of June 30, 2021, the Company had transferred to Goodman approximately $1.3 million of accounts receivable balances.

The amortization of the debt issuance costs and debt discount for the three and six months ended June 30, 2021 was $227 thousand and $445, respectively, and is included in interest expense. Accrued interest related to the Senior Secured Note was $950 thousand and $642 thousand at June 30, 2021 and December 31, 2020, respectively. Interest expense on the Senior Secured Note was $773 thousand and $1.5 million for the three months and six months ended June 30, 2021, respectively. Convertible promissory notes payable, in default (“Seller Note”) - The Company evaluated embedded conversion features within the convertible promissory note and determined that the conversion feature does not require to be bifurcated. Upon adoption of ASC 2020-6 effective January 1, 2021, the convertible promissory note is accounted for as a single liability due to the elimination of the beneficial conversion feature accounting model. April 2021 Securities Purchase Agreement and Warrants (In default) - On April 20, 2021, the Company entered into a Securities Purchase Agreement (the “Leviston Purchase Agreement”), with Leviston Resources, LLC, an accredited investor (“Leviston”) for the sale by the Company in a private placement (the “Private Placement”) of (i) the Company’s future advance convertible promissory note in an aggregate principal amount of up to $3.4 million (the “Leviston Note”) and (ii) a warrant to purchase an additional 16,666,667 shares of common stock of the Company (the “Leviston Warrant”). The Leviston Warrant has an exercise price of $0.18 per share and a four-year term. The closing of the Private Placement occurred on April 20, 2021 (the “Leviston Closing Date”). As noted above, on April 20, 2021, the Company issued the Leviston Note to the Purchaser in an aggregate principal amount of up to $3.4 million (the “Aggregate Amount”), which shall be advanced in disbursements by the Purchaser (“Leviston Disbursements”), as set forth in the Leviston Note. On May 14, 2021, the Leviston Note was amended to increase the Aggregate Amount to $4.2 million. On April 21, 2021, the Purchaser advanced a Leviston Disbursement of $750 thousand, which is net of an original issue discount of 8%. On May 14, 2021, the Purchaser advanced a second Leviston Disbursement of $750 thousand, also net of an original issue discount of 8%. A $250 thousand Leviston Disbursement was made on September 3, 2021, which was subject to the same terms and conditions of the April and May Leviston Disbursements. Warrant issuances to Leviston in April and May 2021 On each of April 20, 2021 and May 14, 2021, the Company also issued 3,968,254 warrants to Leviston for a total of 7,936,508 shares of common stock. The Leviston Warrants contain certain ratchet provisions with respect to subsequent issuances of securities by the Company at a price below the exercise price of such warrants. As a result, the Company determined that these warrants meet the definition of a derivative liability. See details of the associated warrant issuances at Note 11 – Warrants. Embedded Conversion Option The disbursements made in April and May 2021 under the Leviston Notes included a Conversion Option that meets the definition of a derivative liability and, accordingly, is required to be bifurcated. The fair value of Conversion Option liability was determined by using a binomial pricing model. Issuance date (1) Issuance date (1) Binomial Assumptions April 20, 2021 May 14, 2021 June 30, 2021 Change Principal $ 815,217 $ 815,217 $ 1,630,434 Conversion Price (1) $ 0.18 $ 0.18 $ 0.1361 Interest Rate (annual) (2) 0.07 % 0.06 % 0.07 % Volatility (annual) (3) 69.60 % 69.60 % 77.20 % Time to Maturity (Years) 1.0 1.0 0.9 Fair Value of Conversion Option $ 1,354,858 $ 1,385,167 $ 2,844,636 104,611 (1) Based on the terms provided in Convertible Promissory notes dated April 20 and May 14, 2021. (2) Interest rate for U.S. Treasury Bonds, as of each presented period ending date, as published by the U.S. Federal Reserve. (3) Based on the historical daily volatility of the Company as of each presented period ending date. Interest rates on Leviston Notes, Conversion Option, and Loss on Issuance The Leviston Disbursements in April and May 2021 bear interest at the rate of 5% per annum and the default rate of 15%. The Leviston Note contains a conversion option (“Conversion Option”) and because it is in default, the Leviston Note it is convertible into common shares of the Company at a conversion price of 75% of the lowest VWAP during the ten trading days ending on the conversion date. The Conversion Option within the Leviston Note is required to be bifurcated at fair value, which was approximately $1.4 million on the April disbursement and $1.4 million on the May disbursement, and which resulted in additional debt discount being recorded at each disbursement date. Because the combined fair value of the Leviston Warrants and the Conversion Option exceed the face value of the note, the additional amount beyond the face value is recorded as a loss on issuance of $1.4 million on the April disbursement and $1.1 million on the May disbursement. The remaining disbursements up to the Aggregate Amount are subject to the satisfaction of certain terms and conditions set forth in the Leviston Note. Leviston Disbursements bear an interest at a rate of five percent (5%) per annum and have a maturity date of twelve (12) months from the date of issuance. The Leviston Note is convertible at the option of the holder into shares of the common stock of the Company at a conversion price per share equal to the lesser of (i) $0.18, and (ii) ninety percent (90%) of the closing price for a share of common stock reported on the OTCQB on the effective date of the Registration Statement (as defined below). The Leviston Note contains customary events of default and covenants, including limitations on incurrences of indebtedness and liens. Pursuant to the Leviston Purchase Agreement, the Company has agreed, within a reasonable period of time following the Leviston Closing Date, and in any event prior to any Leviston Disbursement under the Leviston Note subsequent to the initial Leviston Disbursement, to enter into a security agreement in favor of the Leviston, securing the Company’s obligations under the Leviston Note. The rights of Leviston to receive payments under the Leviston Note are subordinate to the rights of North Haven Expansion pursuant to a subordination agreement, that the Company and Leviston entered into with North Haven Expansion on April 20, 2021, in connection with the Private Placement (the “Subordination Agreement”). In connection with the Leviston Purchase Agreement, the Company entered into a registration rights agreement with the Leviston on April 20, 2021 (the “Leviston Registration Rights Agreement”) pursuant to which the Company agreed to file a registration statement (the “Registration Statement”) with the SEC no later than thirty days following the Leviston Closing Date for the registration of 100% of the maximum number of the shares issuable upon conversion of the Leviston Note and exercise of the Leviston Warrants issued pursuant to the Leviston Purchase Agreement (the “Leviston Registrable Securities”). The Company shall use its best efforts to keep the Registration Statement continuously effective under the Securities Act of 1933, as amended (the “Securities Act”), until all Leviston Registrable Securities have been sold, or may be sold without the requirement to be in compliance with Rule 144(c)(1) of the Securities Act and otherwise without restriction or limitation pursuant to Rule 144 of the Securities Act, as determined by the counsel to the Company. The Company has yet to file the Registration Statement and, under the terms of the Leviston Registration Rights Agreement, it is obligated to pay in cash a one-time aggregate amount of $250 thousand to the holders of the Leviston Notes, plus 1% of the outstanding principal for each 30-day period during which the Company continues not to have in-place an effective Registration Statement. On August 31, 2021, Leviston notified the Company that it was in default of the Leviston Purchase Agreement effective June 11, 2021 for failure to timely file a Registration Statement. From the date of the default, interest on the amounts due to Leviston is calculated at the default interest rate of 15% in addition to the registration penalties stated above. Convertible promissory notes payable (HealthTronics), in default – As the Seller Note (as defined in Note 10) was not repaid prior to January 1, 2021, HealthTronics may elect to convert the outstanding principal amount plus any accrued but unpaid interest thereon into shares of the Company’s common stock, at a conversion price of $0.10 per share. The Company evaluated embedded conversion features within the convertible promissory note and determined that the conversion feature does not require to be bifurcated. Upon adoption of ASC 2020-6 effective January 1, 2021, the convertible promissory note is accounted for as a single liability due to the elimination of the beneficial conversion feature accounting model. Convertible promissory notes payable (Stolarski), in default – As the Stolarski Note was not repaid prior to January 1, 2021, the holder may elect to convert the outstanding principal amount plus any accrued but unpaid interest thereon into shares of common stock at a conversion price of $0.10 per share. The Company evaluated embedded conversion features within the convertible promissory note and determined that the conversion feature does not require to be bifurcated. Upon adoption of ASC 2020-6 effective January 1, 2021, the convertible promissory note is accounted for as a single liability due to the elimination of the beneficial conversion feature accounting model. SBA Loan #1 - SBA Loan #2 – All or a portion of SBA Loan #2 may be fully or partially forgiven by the SBA upon application by the Company not later than June 2022 in accordance with SBA regulations. The ultimate forgiveness of SBA Loan #2 is also contingent upon regulatory authorities concurring with management’s good faith assessment that the current economic uncertainty made the loan request necessary to support ongoing operations. If, despite the Company’s good-faith belief that given the circumstances the Company satisfied all eligibility requirements for SBA Loan #2, the Company is later determined to have violated any applicable laws or regulations or it is otherwise determined that the Company was ineligible to receive SBA Loan #2, the Company may be required to repay SBA Loan #2 in its entirety and/or be subject to additional penalties. In the event SBA Loan #2, or any portion thereof, is forgiven pursuant to the PPP, the amount forgiven is applied to outstanding principal. As of June 30, 2021, $23 thousand is included in current liabilities and the remainder of the $1.0 million loan balance is included in non-current liabilities in the accompanying Condensed Consolidated Balance Sheets.

Contingencies [Abstract]
Contingencies	14. Contingencies Supplier disputes - In May 2021, the Company received notification alleging that it is not in compliance with the license agreement with Celularity entered into in connection with the acquisition of the UltraMIST assets. The Company has responded and asserted that the Company is not in breach and that the supplier has breached various agreements. It is too early to determine the outcome of this matter. Any potential impact to the Company cannot be fully determined at this time and there is no guarantee that the dispute will be resolved in a manner beneficial to the Company or at all. As part of the Asset Purchase Agreement on August 6, 2020, the Company assumed obligations for a purchase order for UltraMIST devices from Celularity’s vendor Minnetronix. This purchase order had a remaining purchase commitment of approximately $1.1 million. The purchase order also calls for production delay fees of 1.25% of the committed inventory if the Company delays production. There is also a cancelation clause of 20% of the remaining balance in the event that the Company delays production for more than six months. On September 23, 2021, Minnetronix notified the Company that it was cancelling the purchase order for the UltraMIST devices as a result Company delaying production more than six months. This notification includes fees and charges for the cancellation of the purchase order of an additional $320 thousand. The Company expects to be able to resume production upon paying this obligation. While the Company is disputing certain aspects of this termination notice and is continuing to engage with Minnetronix regarding resolution of this matter, including reinstatement of the purchase order, there is no guarantee that the dispute will be resolved in a manner beneficial to the Company or at all.

Income Taxes [Abstract]
Income Taxes	16. Income Taxes The provision for income taxes of $6 thousand and $22 thousand, for the three months and six months ended June 30, 2021 and the deferred tax liability are related to the goodwill of $7.3 million recorded as part of the acquisition of the Celularity assets and is known as a “naked credit”. The goodwill was assigned an indefinite life for book purposes but is deductible for income tax purposes over a fifteen-year life. As a result, the deferred tax liability has an indefinite life and cannot be used as a source of taxable income to support the realization of other deferred tax assets.

Subsequent Events [Abstract]
Subsequent Events	17. Subsequent Events September 2021 Securities Purchase Agreement and Warrants (In default) - Under the terms of the September 2021 Purchase Agreements, the aggregate principal amount of the September 2021 Notes of up to $543 thousand (the “Aggregate Amount”), may be advanced in disbursements by the September 2021 Purchasers (“September 2021 Purchasers Disbursements”), as set forth in the September 2021 Notes. The September 2021 Purchasers Disbursements bear an interest at a rate of five percent (5%) per annum and have a maturity date of twelve (12) months from the date of issuance. Each September 2021 Note is convertible at the option of the holder into shares of common stock of the Company at a conversion price per share equal to (A) until the date of effectiveness of the Registration Statement, $0.18 and (B) after the date of effectiveness of the Registration Statement, the lesser of (i) $0.18, (ii) ninety percent (90%) of the closing price for a share of common stock reported on the OTCQB on the effective date of the Registration Statement or (iii) 75% of the lowest volume weighted average price, as defined,, which shall be no lower than $0.01. The September 2021 Notes contain customary events of default and covenants, including limitations on incurrences of indebtedness and liens. Pursuant to each September 2021 Purchase Agreement, the Company entered into a security agreement in favor of the applicable September 2021 Purchaser, securing the Company’s obligations under the applicable September 2021 Note. The rights of each September 2021 Purchaser to receive payments under their respective note is subordinate to the rights of North Haven Expansion pursuant to a Subordination Agreement, that the Company and each September 2021 Purchaser entered into with North Haven Expansion in connection with the September 2021 Private Placement. In connection with each September 2021 Purchase Agreement, the Company entered into a registration rights agreement with the September 2021 Purchasers on September 3, 2021 (the “September 2021 Purchasers Registration Rights Agreement”) pursuant to which the Company has agreed to file a Registration Statement no later than ninety (90) days following the September 2021 Purchasers Closing Date for the registration of 100% of the maximum number of the shares issuable upon conversion of the September 2021 Notes and exercise of the September 2021 Warrants issued pursuant to such September 2021 Purchase Agreement (the “September 2021 Purchasers Registrable Securities”). The Company shall use its best efforts to keep the Registration Statement continuously effective under the Securities Act of 1933, as amended, until all September 2021 Purchasers Registrable Securities have been sold, or may be sold without the requirement to be in compliance with Rule 144(c)(1) of the Securities Act and otherwise without restriction or limitation pursuant to Rule 144 of the Securities Act, as determined by the counsel to the Company. The September 2021 Notes were in default as of October 25, 2021 and, accordingly, on that date, interest began accruing at the default rate of 15% in addition to registration penalties per the September 2021 Purchasers Registration Rights Agreement. The Company has yet to file the Registration Statement, and under the terms of the September 2021 Registration Rights Agreement, it is obligated to pay in cash a one-time aggregate amount of $250 thousand to the holders of the September 2021 Notes, plus 1% of the outstanding principal for each 30-day period during which the Company continues not to have in-place an effective Registration Statement. As a result of this breach of the September 2021 Registration Rights Agreement, interest on the September 2021 Notes accrues at the default interest rate of 15%. September 2021 and December 2021 Advances on Future Receipts Financing – On December 22, 2021, the Company paid off the remaining balance of $650 thousand from the September 27, 2021 advance and received $758 thousand in cash proceeds related to its entry into a non-recourse agreement for the sale of $1.5 million of future receipts to GCF. In conjunction with the 24-week agreement, the Company is obligated to remit to GCF a minimum of $59 thousand of receipts each week for the first six weeks and receipts of $98 thousand for the remaining 18 weeks. After considering the payments made at closing, the Company will record an initial liability of $1.5 million and a debt discount of approximately $90 thousand, which represents the original issue discount and the fees paid in conjunction with the financing. The debt discount will be amortized to interest expense over the life of the agreement. The Company will begin making the required minimum weekly payments January 3, 2022 and is obligated to continue through June 13, 2022. At closing, October 2021 Advances from Directors - In exchange for the Nemelka Advance, the Company issued to NightWatch Capital Advisors, LLC a promissory note in the principal amount of $25 thousand (the “Nemelka Note”). The Nemelka Note matures on June 30, 2022 and accrues interest at a rate equal to 15.0% per annum. In exchange for the Stolarski Advance, as well as the $125 thousand deposit received in March 2021 by the Company (see Note 16), the Company issued to Mr. Stolarski a promissory note in the principal amount of $150 thousand (“Stolarski Note #2”). Stolarski Note #2 matures on June 30, 2022 and accrues interest at a rate equal to 15.0% per annum.

Summary of Significant Accounting Policies [Abstract]
Estimates	Estimates Significant estimates include the recording of allowances for doubtful accounts, the net realizable value of inventory, useful lives of long-lived assets, fair value of goodwill and other intangible assets, the determination of the valuation allowances for deferred taxes and the estimated fair value of embedded derivatives, including warrants and embedded conversion options on convertible debt issuances.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets – Intangibles-Goodwill and Other
Fair value of financial instruments	Fair value of financial instruments - The carrying values of accounts payable, and other short-term obligations approximate their fair values, because of the short-term maturities of these instruments. The Company utilizes the guidance of ASC Topic 820-10, Fair Value Measurements (“ASC 820-10”), which defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. The framework that is set forth in this standard is applicable to the fair value measurements where it is permitted or required under other accounting pronouncements. The ASC 820-10 hierarchy ranks the quality and reliability of inputs, or assumptions, used in the determination of fair value and requires financial assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) in active markets for identical assets and liabilities; • Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and • Level 3 - Unobservable inputs that are not corroborated by market data, therefore requiring the Company to develop its own assumptions. The Company recognizes all derivatives on the Condensed Consolidated Balance Sheet at fair value. Each of the pricing models includes the use of unobservable inputs such as the expected term, anticipated volatility and risk-free interest rate, and therefore, is classified within Level 3 of the fair value hierarchy.
Recent Accounting Pronouncements	Recent Accounting Pronouncements – Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity In May 2021, the FASB issued ASU 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). In December 2019, the FASB issued ASU 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment. The amendments in ASU 2017-04 modified the testing that an entity should perform for its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. This amendment is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2017-04 effective January 1, 2021. The adoption of this guidance did not impact our results of operations or financial position.
