TEMPERATURE SENSING OF IMPLANTED WIRELESS RECHARGE COIL

The present disclosure provides a transcutaneous energy transfer system (TETS), having an implantable receiving coil in communication with an implantable controller and a hermetically sealed package encased by the implantable receiving coil. The hermetically sealed package including a plurality of tuning capacitors, at least one temperature sensor, scavenging circuitry configured to scavenge power from the plurality of tuning capacitors, and a temperature measuring circuit in communication with the at least one temperature sensor and the scavenging circuitry. The at least one temperature sensor being configured to measure a temperature of the hermetically sealed package and the temperature measuring circuit being configured to transmit the measured temperature to the implantable controller.
