ABSTRACT:
An infrared radiation detecting device is provided that comprises a substrate, an infrared radiation absorbing unit, at least one support beam and a thermopile. The at least one support beam has a first end portion coupled to the substrate and a second end portion coupled to the infrared radiation absorbing unit. The thermopile includes first and second electrical conductors disposed on the support beam with the first and second electrical conductors having different electric conductivities. The first and second electrical conductors is dimensioned and shaped to improve structural rigidity of the support beam in comparison to an identically shaped support beam including a thermopile with a pair of first and second electrical conductors that are identically shaped and disposed parallel to each other.
