Abstract
An apparatus, system, and method for neurostimulation by high frequency ultrasound. In one embodiment, an apparatus includes a pulse generator, an ultrasound transducer coupled to the pulse generator, and an implantable stimulator. The implantable stimulator may include a piezoelectric element configured to convert ultrasound signals from the ultrasound transducer into electrical signals, a rectifier configured to convert alternating current from the piezoelectric element to a monophasic current, a capacitor coupled to the rectifier, and a first electrode and a second electrode coupled to the rectifier and capacitor and configured to transmit the monophasic current to body tissue. In addition, the apparatus may include a current-limiting circuit configured to limit the amount of current transmitted to the body tissue.
