ABSTRACT:
Thermal sensor (36) mounted to a substrate (34). The thermal sensor may include a first thin film electrode (52), a nucleation element (55), a thermally sensitive element (50) and a second thin film electrode (54). The first thin film electrode (52) may be disposed adjacent to the nucleation element(52). The thermally sensitive element (50) may be in electrical communication with the first thin film electrode (52). The thermally sensitive element (50) may comprise a plurality of preferentially-ordered crystals. The second thin film electrode (54) may be in electrical communication with the thermally sensitive element (50) opposite the nucleation element (55).
