Abstract:
A thermoelectric device comprising: ,a high thermal conductivity and high electrical resistivity substrate adapted for thermal coupling with a first higher-temperature surface, coupled to allow heat to flow between the high temperature surface and the substrate; and at least 1000 thermoelectric legs, each said thermoelectric leg having a diameter less than or equal to 60 &mgr;m, and comprising: a thermoelectric film material in thermal couple with the substrate; and a multilayer stack structure disposed between the substrate and the thermoelectric material, the multilayer stack structure comprising thermally and electrically conductive layers for supplying heat between the substrate and the thermoelectric material and also conducting current from the thermoelectric material, wherein at least a plurality of said at least 1000 thermoelectric legs are electrically in series and thermally in parallel.
