Patent number: 8399883Abstract: The present invention provides a nitrogen-oxide gas sensor that is able to measure nitric oxide and nitrogen dioxide at the same time and ensure measurement accuracy and long stability. For these purposes, the nitrogen-oxide gas sensor includes: an oxide ion conductive solid electrolyte; a primary film that contacts the solid electrolyte and is made of a p-type semi-conductor metal oxide; a secondary film that contacts the solid electrolyte and is made of a p-type semiconductor metal oxide; an n-type semiconductor metal oxide that is included in at least one of the primary and secondary films; a power source that applies electric power to the primary and secondary films by electrically connecting a primary node to the primary film and a secondary node to the secondary film; and a measurement unit that measures the electric potential difference between the primary and secondary nodes.Type: GrantFiled: September 30, 2009Date of Patent: March 19, 2013Assignees: Iljin Copper Foil Co., Ltd., Cios Inc.Inventors: Jin Su Park, Byung Young Yoon, Jung Won Park, Jung Hwan Cho, Sang Beom Kim
