Abstract:
1. A leadless system for deep brain stimulation of a subject based on time-reversal acoustics, the system comprising: a first implantable stimulator in a hermetically sealed housing, said stimulator in turn comprising: an external assembly comprising: wherein said external assembly is configured to emit a first initial unfocused acoustic wave signal, said first piezoelectric receiving transducer is configured to receive said first unfocused acoustic wave signal after reverberation in a skull of the subject and generate an electromagnetic radiofrequency feedback signal, said external assembly is further configured to receive said radiofrequency feedback signal, time-reverse thereof and generate a first driving signal to cause said emitting acoustic transducer to send a first acoustic wave signal focused on said first piezoelectric receiving transducer to generate electrical energy sufficient to operate said first implantable stimulator for the purpose of deep brain stimulation.
