ABSTRACT:
A thermal sensor (36, 84, 114) comprising a thermal assembly (44, 88, 118) and a signal flowpath (46, 90, 120). The thermal assembly (44, 88, 118) may comprise a thermally sensitive element (50) and a pair of electrodes (52, 54). The thermally sensitive element (50) may generate a signal representative of an amount of thermal radiation incident to the thermally sensitive element (50). The electrodes (52, 54) may collect the signal generated by the thermally sensitive element (50). The signal flowpath (46, 90, 120) may transmit the signal collected by the electrodes (52, 54) to the substrate (34, 82, 112). The signal flowpath (46, 90, 120) may comprise a pair of arms (56, 58, 92, 122) each extending from an electrode (52, 54) and be connected to the substrate (34, 82, 112). The arms (56, 58, 92, 122) may support the thermal assembly (44, 88, 118) in spaced relation with the substrate (34, 82, 112). The arms (56, 58, 92, 122) may be formed of a thermally insulating material.
