Abstract
An implantable, rechargeable assembly that contains an implantable device within a living organism; an electrical storage device is connected to the implantable device, and a thermoelectric charging assembly is connected to said electrical storage device. A thermoelectric charging assembly contains devices for transferring thermal energy between the living organism and a thermoelectric module, for creating an electrical current of a first polarity from thermal energy, for creating an electrical current with a second polarity from thermal energy, for charging the electrical storage device with the electrical current of said first polarity, and for charging the electrical storage device with the electrical current of the second polarity.
