摘要： An infrared sensing element of the present invention includes a base including a thin film portion and a thick wall portion arranged around the thin film portion, and a thermopile including a plurality of thermocouples connected in series so that cold junctions are located on the thick wall portion and hot junctions are located on the thin film portion, wherein a thermosensitive portion is provided in contact with the thick wall portion so that a reference temperature with high accuracy can be used for determining temperature based on output from the thermopile. A PN junction formed on a semiconductor substrate serves as the thermosensitive portion, and it is used to provide for a compact infrared sensing element with high performance at low cost.

摘要： The invention is directed to a thermopile sensor and in particular to a radiation thermometer or a motion detector with a thermopile sensor. The thermopile sensor includes a thermopile supported in a housing. The thermal capacity of the cold and hot junctions of the thermopile including its supporting structure and the thermal conductivity of the supporting structure are mutually coordinated such that a change in the housing's temperature produces a change of equal magnitude in the cold and hot junctions' temperature, that is, no temperature gradients occur within the thermopile.

摘要： A ferroelectric/pyroelectric infrared detector includes a lattice matched substrate material and a colossal magneto-resistive electrode material. In a second embodiment, the ferroelectric/pyroelectric detector includes a colossal magneto-resistive template material to accommodate the use of a non-lattice matched substrate material, and a colossal magneto-resistive electrode material. The embodiments of the present invention provide a semi-transparent electrode material of the requisite lattice constant value, crystal orientation, and chemical compatibility. Additional advantages associated with the invention include the ability to provide the desired resistance behavior by varying the composition of the colossal magneto-resistive material, the ability to tune the colossal magneto-resistive transition temperature to be near the device operating temperature through appropriate selection of materials and process conditions, and the ability to ensure the crystal oriented growth of the ferroelectric/pyroelectric thin film. By selecting an appropriate colossal magneto-resistive electrode material, the performance of the ferroelectric/pyroelectric detector can be improved over that associated with the use of conventional electrodes such as “normal” metals or metal oxides.
