Abstract:
Efficient power transmission from an acoustic transmitter to an electrical load on an implanted device is provided using a control system that at least varies the transmitted acoustic frequency. Varying the transmitted frequency can change the electrical impedance of the acoustic transducer in the receiver that receives power from the transmitter. This ability to vary the transducer impedance can be used to optimize power delivery to the load.
