Abstract:
1. A thermoelectric cooling and heating device comprising: a substrate; a plurality of thermoelectric elements arranged on one side of the substrate and configured to perform at least one of selective heating and cooling, each thermoelectric element including, a thermoelectric material, a Peltier contact contacting the thermoelectric material and configured to form under electrical current flow at least one of a heated junction and a cooled junction, and electrodes configured to provide current through the thermoelectric material and the Peltier contact; and a controller configured to separately control at least a first electrode of a first thermoelectric element and a second electrode of a second thermoelectric element, the controller being further configured to bias the first and second electrodes to provide simultaneous heating of a first portion of the substrate adjacent the first thermoelectric element and cooling of a second portion of the substrate adjacent the second thermoelectric element.
