Power generation for implantable devices
First Claim
1. A cranially disposed thermoelectric power generator having a first surface which is an approximately extra-cranially disposed dorsal surface and said second surface is an approximately intra-cranially disposed ventral surface, and which is configured to generate electricity based upon a thermal gradient which occurs between said first and seconds surface.

Abstract
An implantable, rechargeable medical system comprised of an implanted device, a power storage device connected to the implantable device, and a charging device operatively connected to the electrical storage device. The charging device can be thermoelectric and have components for transferring thermal energy from an intracranial heat accumulator to an extra-cranial heat sink, for generating an electrical current from the thermal energy transfer, for charging the electrical storage device using the electrical current, for measuring power generation, usage and reserve levels, for measuring temperatures of the intracranial and extra-cranial components, for physically disrupting heat transfer and charging operations, and for generating signals relevant to the status of temperature and electricity transfer in relation to energy generation criteria. The system may also have long-range and short range wireless power harvesting capability as well as movement, and photovoltaic charging capability. Components may be dual purpose, being used for receiving wireless energy as well as for accomplishing other operations such as sensing or stimulating. Specialized accessories assist with providing enhanced wireless power charging.
