Claim 0:
1. A thermoelectric element comprising: a thermoelectric body, a first contact structure, and a second contact structure, wherein the first contact structure comprises at least one first porous metal structure and at least one metal layer, wherein
the at least one first porous metal structure is at least partially embedded within a first outer region of the thermoelectric body;
the at least one metal layer comprises a first metal layer and a second metal layer;
the at least one metal layer is overlying an outer surface of the first outer region of the thermoelectric body and the first metal layer is in direct contact with the at least one first porous metal structure;
each of the at least one first porous metal structure, the first metal layer, and the second metal layer comprise nickel; and
the first metal layer has a thickness of at least 10 nm and not greater than 2000 nm and the second metal layer has a thickness of at least 3 microns and not greater than 200 microns, and a stress of the second metal layer is lower than a stress of the first metal layer.
