Abstract:
A thermal sensor to provide an image representative of the amount of thermal radiation incident to the thermal sensor, comprising:a substrate having a surface;a thermally sensitive element spaced above the surface of the substrate;a first thin film electrode including a plurality of spaced digits, the first thin film electrode being provided on a side of the thermally sensitive element opposite from the substrate;a second thin film electrode including a plurality of spaced digits, the second thin film electrode being provided on the same side of the thermally sensitive element as the first thin film electrode, the digits of the first thin film electrode being in spaced interposed relation to the digits of the second thin film electrode; anda supporting structure to support the first and second thin film electrodes in the spaced relation above the surface of the substrate, the supporting structure including:at least two conductive posts extending upwardly from the surface of the substrate; anda pair of arms which each extend outwardly from a respective one of the electrodes and are each connected to a respective one of the posts.
