20110168557NITROGEN-OXIDE GAS SENSOR - A nitrogen-oxide gas sensor that is able to measure a nitric oxide and a nitrogen dioxide at the same time, and ensure sensing accuracy and stability over a long period of time.07-14-2011
20110168556NITROGEN-OXIDE GAS SENSOR - 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. The present invention relates to the nitrogen-oxide gas sensor that includes: an oxide ion conductive solid electrolyte; a primary film made of a metal oxide which contacts the solid electrolyte; a secondary film made of a metal oxide that contacts with the solid electrolyte and is separated from the first film; 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; a tertiary film made of a metal oxide that contacts the solid electrolyte, wherein the tertiary film and the primary film are connected to the power source in parallel; and a measurement unit that measures the electric potential difference between the primary and secondary nodes.07-14-2011
20110163314NITROGEN-OXIDE GAS SENSOR WITH LONG SIGNAL STABILITY - 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.07-07-2011
