Claim:
1. A thermoelectric device comprising: a middle substrate comprising a single layer; a plurality of N-type thermopiles and P-type thermopiles disposed on a first surface of the single layer of the middle substrate, wherein the N-type thermopiles and the P-type thermopiles are alternately arranged and are electrically connected to each other in series; a first substrate that is thermally bonded to the first surface of the single layer of the middle substrate, such that the first substrate is directly thermally bonded to a region of the single layer of the middle substrate at a first side of each of the plurality of N-type thermopiles and to a region of the single layer of the middle substrate at a first side of each of the plurality of P-type thermopiles, and wherein the first substrate is not in physical contact with any of the plurality of N-type thermopiles and is not in physical contact with any of the plurality of P-type thermopiles and a second substrate that is thermally bonded to a second surface of the single layer of the middle substrate, such that the second substrate is directly thermally bonded to a region of the single layer of the middle substrate at a second side, opposite the first side, of each of the N-type thermopiles and to a region of the single layer of the middle substrate at a second side, opposite the first side, of each of the P-type thermopiles, and wherein the second substrate is not in physical contact with any of the plurality of N-type thermopiles and is not in physical contact with any of the plurality of P-type thermopiles.
