PLANAR THERMOELECTRIC GENERATOR

A thermoelectric generator may comprise a pair of thermally conducive top and bottom plates having a foil assembly positioned therebetween. The foil assembly may comprise a substrate having a series of alternating thermoelectric legs formed thereon. The thermoelectric legs may be formed of alternating dissimilar materials arranged in at least one row. Each one of the thermoelectric legs may define a leg axis oriented in non-parallel relation to the row axis. Thermally conductive strips mounted on opposite sides of the substrate may be aligned with opposite ends of the thermoelectric legs in the rows such that one end of the thermoelectric legs is in thermal contact with the top plate and the opposite end of the thermoelectric legs is in thermal contact with the bottom plate. The thermally conductive strips define thermal gaps between the thermoelectric legs and the top and bottom plates causing heat to flow lengthwise through the thermoelectric legs resulting in the generation of electrical voltage.
