Gentlemen:

We are acting as counsel to Akoustis Technologies, Inc., a Nevada corporation (the “Company”), in connection with the filing with the Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933, as amended (the “Securities Act”), of a Registration Statement on Form S-1 (the “Registration Statement”), relating to the offer and sale pursuant to the Registration Statement, by the selling stockholders identified in the Registration Statement (the “Selling Stockholders”), of up to 7,876,310 shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (the “Common Stock”), consisting of 5,655,608 issued and outstanding shares of Common Stock, 324,650 shares of Common Stock issuable upon exercise of Common Stock purchase warrants and up to 1,896,052 shares of Common Stock issuable pursuant to the price protected anti-dilution provision applicable to 3,797,104 of the 5,655,000 issued and outstanding shares referenced above.

You have requested our opinion as to the matters set forth below in connection with the issuance of the Shares.  For purposes of rendering this opinion, we are familiar with the Registration Statement, and we have examined the Company’s Articles of Incorporation, as amended to date, the Company’s Bylaws, as amended to date, and corporate actions of the Company that provided for the issuances of the Shares.  We have also examined such other documents, certificates, instruments and corporate records, and such statutes, decisions and questions of law as we have deemed necessary or appropriate for the purpose of this opinion.  We have examined and relied upon certificates of public officials and, as to certain matters of fact that are material to our opinion, we have also relied on statements of an officer of the Company.

Based upon and subject to the foregoing, it is our opinion that:

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name in the prospectus constituting a part thereof.
