Claim Text:
1. A microdevice for calorimetric measurement, comprising: a first thermally isolated microchamber comprising a first serpentine structure, and a second thermally isolated microchamber comprising a second serpentine structure, each of the first and second serpentine structures have a plurality of long serpentine edges and a plurality of short serpentine edges; a thin film substrate; wherein the first thermally isolated microchamber and the second thermally isolated microchamber are each supported on the thin film substrate, wherein the thin film substrate has a first side constituting a floor of the first and second thermally isolated microchambers and a second side opposing the first side, and wherein the thin film substrate comprises a thermoelectric sensor, the thermoelectric sensor configured as a thin layer thermopile comprising a plurality of adjacent segments of dissimilar materials, each of the adjacent segments joined together at opposite ends forming a plurality of thermocouple junctions, the thermocouple junctions oriented serially along the long serpentine edges of the first and second serpentine structures of the first and second thermally isolated microchambers, the thermocouple junctions disposed under each of the first and second thermally isolated microchambers and configured to measure the temperature differential between the first and second thermally isolated microchambers.
