1. A system for acoustic energy into a human body comprising:
- an array of acoustic transducers configured to transmit acoustic energy into the body;
circuitry for focusing the acoustic energy at specific regions in the body;
an acoustic receiver adapted to receive the focused acoustic energy and convert the acoustic energy into electrical energy;
a pair of electrodes connected to the acoustic receiver and adapted to transfer the electrical energy through the body;
wherein the circuitry is further configured to detect the electrical energy transferred through the body by the pair of electrodes to determine whether the acoustic energy is focused on the acoustic receiver.

Abstract
Method and systems for optimizing acoustic energy transmission in implantable devices are disclosed. Transducer elements transmit acoustic locator signals towards a receiver assembly, and the receiver responds with a location signal. The location signal can reveal information related to the location of the receiver and the efficiency of the transmitted acoustic beam received by the receiver. This information enables the transmitter to target the receiver and optimize the acoustic energy transfer between the transmitter and the receiver. The energy can be used for therapeutic purposes, for example, stimulating tissue or for diagnostic purposes.
