Abstract:
1. A neurostimulator, comprising: an ultrasound pulse generator; an ultrasound transducer connected to the ultrasound pulse generator; and an electrode system capable of being acoustically connected to the ultrasound transducer and the ultrasound pulse generator, wherein the electrode system comprises a plurality of separate piezoelectric chips configured so that at least a first piezoelectric chip and a second piezoelectric chip can be differentially placed proximate a nerve bundle, wherein the plurality of piezoelectric chips are small enough to be implanted using a standard gauge syringe close to a nerve fiber in an individual, wherein each piezoelectric chip comprises (i) a pair of electrodes, (ii) a piezoelectric material electrically connected to the pair of electrodes; and (iii) a diode in electrical communication with the pair of electrodes and the piezoelectric material.
