Title:
GAS SENSOR, CONTAINED COMPONENT SENSING DEVICE PROVIDED WITH GAS SENSOR, INSPECTION SYSTEM PROVIDED WITH GAS SENSOR, GAS SENSOR INSPECTION METHOD, AND METHOD FOR MANUFACTURING GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/184721
Kind Code:
A1
Abstract:
A gas sensor provided with: an electroconductive membrane (22) flexed by an applied surface stress; a fixing member (24) disposed further to the outside than the membrane (22); a linking part (26) for linking the membrane (22) and the fixing member (24); a flexible resistance (28), the resistance value of which varies in accordance with bending occurring in the linking part (26); an electroconductive support substrate (10) connected to the fixing member (24) and disposed so as to be provided in a gap (40) between the membrane (22) and the linking part (26); a receiving body (30) formed on a region including the center of a surface which is a surface on the reverse side from the surface of the membrane (22) facing the support substrate (10), the receiving body (30) producing a deformation corresponding to an adsorbed substance; a first terminal (50a) capable of applying a first potential to the membrane (22); a second terminal (50b) capable of applying a second potential to the support substrate (10); and an insulation part (6) for electrically insulating the fixing member (24) and the support substrate (10).
