A thermoelectric cooling and heating device including 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 such that each thermoelectric element includes a thermoelectric
material, a Peltier contact contacting the thermoelectric material and
forming 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. As such, the
thermoelectric cooling and heating device selectively biases the
thermoelectric elements to provide on one side of the thermolectric
device a grid of localized heated or cooled junctions.
