Patent ID: 8649875

Claim:
A time-reversal acoustics system for remote generation of electrical signal in tissue, the system comprising: a first receiver including in a hermetically sealed housing: a first piezoelectric receiving transducer, an internal electrical circuit with an input operably coupled to said first receiving transducer, a first antenna configured for emitting a first radiofrequency signal, said first antenna operably coupled to said first receiving transducer, a first stimulating electrode operably coupled to an output of said internal electrical circuit, said first stimulating electrode is configured to be engaged with the tissue, and a transmitter including: a time-reversal electronic unit, a radiofrequency signal receiver with an input operably coupled with a radiofrequency antenna and an output operably coupled with an input of said time-reversal electronic unit, an emitting acoustic transducer with an input operably coupled to an output of said time-reversal electronic unit, wherein said time-reversal electronic unit is configured to provide said emitting acoustic transducer with a driving signal formed by time-reversing of the radiofrequency signal received from said first receiver in response to an acoustic wave signal generated by said emitting acoustic transducer; said driving signal causing said emitting acoustic transducer to send a high intensity acoustic wave signal focused on said first piezoelectric receiving transducer to generate electrical energy sufficient to operate said first stimulating electrode to generate said electrical signal in the tissue.
