发明名称 Thermopile-based gas sensor
摘要 A method of manufacturing a sensor is provided. The method includes disposing a sacrificial layer on a substrate, disposing a low-thermal-conductivity layer on the sacrificial layer, and disposing a first set of conductive arms and a second set of conductive arms on the low-thermal-conductivity layer to form a plurality of thermal junctions. The plurality of thermal junctions is adapted to form a plurality of hot junctions and a plurality of cold junctions when subjected to a difference in temperature. The method also includes removing the sacrificial layer and a portion of the low-thermal-conductivity layer to form a cavity therein. The cavity is configured to provide insulation for the plurality of hot junctions. A thermopile sensor is also provided, and a calorimetric gas sensor implementing the thermopile sensor is provided.
