A microwatt thermoelectric generator suitable for implanting in the body. The disclosed generator utilizes a nuclear energy source. Provision is made for temporary electrical connection to the generator for testing purposes, and for ensuring that the heat generated by the nuclear source does not bypass the pile. Also disclosed is a getter which is resistant to shrinkage during sintering, and a foil configuration for controlling the radiation of heat from the nuclear source to the hot plate of the pile.

Microwatt thermoelectric generator

Athermopile for a microwatt thermoelectric generator suitable for implanting in the body. The thermopile comprises a series of semiconductive thermoelectric elements such as P- and N-type bismuth telluride deposited as a thin film on a substrate such as a polyimide by sputtering. After the thin film is deposited, the thermopile is heat treated to anneal the bismuth telluride. The thermopile is then ready for insertion in a microwatt thermoelectric generator.

Thermopile for microwatt thermoelectric generator

Novel header for use in nuclear applications comprised of a base containing at least one bore, a niobium terminal passing through said bore sealed in an alumina plug which, in turn, is sealed in a bore defined in the base.
