EVALUATION OF THE POWER-GENERATION CAPACITY OF IMPLANTABLE THERMOELECTRIC POWER GENERATOR DRIVEN BY RADIOISOTOPE FUEL

摘要

The unique merit of the implantable thermoelectric generator lies in its direct utilization of the temperature difference intrinsically existing throughout the whole biological body. Therefore, it can resolve the service life mismatch between the IMD and its battery. In order to promoting the TEG maximum power, a piece of radioisotope fuel was fixed on the TEG hot junction. Recurring to the thermal energy released during disintegration of radioactive isotope, it can guarantee a marked promotion in the temperature difference across the implanted TEG; consequently apply enough power for the IMDs.
