Abstract
A housing placeable against skin of a subject includes a transmitting coil. Battery-powered control circuitry including a power stage transmits power to an implant by activating the power stage to drive a current through the transmitting coil to induce an induced current in a receiving coil of the implant. A sensor indicates divergence of a real-time resonance frequency of the transmitting coil with respect to a reference resonance frequency of the transmitting coil at which (a) efficiency of the power stage is at least 70% of a maximum efficiency as a function of the resonance frequency, and (b) the current driven through the transmitting coil is less than 96% of a maximum current drivable through the transmitting coil as a function of the resonance frequency. The circuitry reduces the divergence by tuning the resonance frequency of the transmitting coil. Other applications are also described.
