Title: Gas detector and gas detection method
Inventor: MURAOKA SHUNSAKU
IPC: G01N27/04
Filed: 2017-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a gas detector which can detect a hydrogen-containing gas sensitively and has an excellent power saving property.SOLUTION: A gas detector includes a gas sensor and a power source circuit. The gas sensor includes: a first electrode; a second electrode; a metal oxide layer located between the first and second electrodes; and an insulating layer covering the first electrode, the second electrode, and the metal oxide layer and having an opening making a part of the main surface of the second electrode exposed. The resistance value of the metal oxide layer drops when a gas containing hydrogen atoms becomes in contact with the second electrode. The power source circuit increases the resistance value of the metal oxide layer by applying a predetermined voltage between the first and second electrodes before and/or after the resistance value of the metal oxide layer drops.SELECTED DRAWING: Figure 8A
