3. An implantable receiver-stimulator, comprising:
an enclosure extending along a longitudinal axis and having an inner surface and an outer surface;
a plurality of acoustic transducers mounted to the inner surface and distributed circumferentially about the inner surface relative to the longitudinal axis, wherein individual ones of the acoustic transducers (a) have a base portion mounted to the inner surface of the enclosure and defining an aperture for receiving acoustic power from an acoustic field along an acoustic axis extending orthogonal to the longitudinal axis and (b) are configured to convert the received acoustic power to electrical power, and wherein individual ones of the acoustic transducers are non-isotropic; and
at least one electrode configured to receive the electrical power from the acoustic transducers and deliver at least a portion of the electrical power to tissue.
