Thin-film thermoelectric cooling and heating devices for DNA genomic and proteomic chips, thermo-optical switching circuits, and IR tags
A thermoelectric cooling and heating device including asubstrate, a plurality of thermoelectric elements arranged on oneside of the substrate and configured to perform at least one ofselective heating and cooling such that each thermoelectric elementincludes a thermoelectric material, a Peltier contact contactingthe thermoelectric material and forming under electrical currentflow at least one of a heated junction and a cooled junction, andelectrodes configured to provide current through the thermoelectricmaterial and the Peltier contact. As such, the thermoelectriccooling and heating device selectively biases the thermoelectricelements to provide on one side of the thermolectric device a gridof localized heated or cooled junctions.
