1. An implantable neurostimulator comprising:
a first electrode electrically coupled to a first piezoelectric material; a second electrode electrically coupled to the first piezoelectric material; a third electrode electrically coupled to a second piezoelectric material; a fourth electrode electrically coupled to the second piezoelectric material; where the first piezoelectric material is configured to provide an electrical potential to biological tissue through the first and second electrodes in response to an ultrasound signal; where the second piezoelectric material is configured to provide an electrical potential to biological tissue through the third and fourth electrodes in response to an ultrasound signal; where the first and second piezoelectric materials have different resonant frequencies; and where the first piezoelectric material is a polymer.
