Abstract: A thermoelectric unit includes a thermoelectric membrane having a first surface at a cavity in a layer of first thermally conductive material. The thermoelectric membrane has a second surface opposite to the first surface with second thermally conductive material arranged in contact with the second surface of the thermoelectric membrane. The thermoelectric membrane includes thermally sensitive material configured to generate via the Seebeck effect a thermoelectric signal indicative of the temperature difference between the second thermally conductive material and the first thermally conductive material. An insulating molding compound is molded onto the second thermally conductive material arranged in contact with the second surface of the thermoelectric membrane wherein mechanical stress develops in the thermoelectric membrane in response to molding. An encapsulation is provided at the second surface of the thermoelectric membrane. The encapsulation counters mechanical stress developed in the thermoelectric membrane in response to the molding of insulating molding compound.
