Patent number: 9546948Abstract: A gas sensor is proposed, which can detect a gas by a novel configuration while reduction in size is achieved. The gas sensor (1) does not need a light absorption path as in a prior art so that the size can be reduced correspondingly. Further, in the gas sensor (1), a gas is absorbed in an ionic liquid (IL), and a dielectric constant of the ionic liquid (IL) that changes by absorbing the gas can be measured according to a change in light intensity that occurs by a surface plasmon resonance phenomenon in a metal layer (7). Thus, the gas sensor (1) including the novel configuration that can detect a gas based on the change in the light intensity can be realized.Type: GrantFiled: December 27, 2012Date of Patent: January 17, 2017Assignees: The University of Tokyo, Omron CorporationInventors: Isao Shimoyama, Kiyoshi Matsumoto, Tetsuo Kan, Yusuke Takei, Hidetoshi Takahashi, Koutaro Ishizu, Masahito Honda

Patent number: 9250210Abstract: A gas sensor that can enhance gas detection sensitivity more than the conventional sensors with a simple configuration is proposed. An electric double layer including a gate insulating layer is formed in an ionic liquid (IL), a change of a state of the gate insulating layer in the ionic liquid (IL) that occurs by absorbing a gas is directly reflected in a source-drain current (Isd) that flows in a carbon nanotube (8). Therefore, the gas detection sensitivity can be enhanced more than in the conventional sensors. Further, since the ionic liquid (IL) can be simply provided on a substrate (2) to be in contact with the carbon nanotube (8) and a gate electrode (7), the configuration that chemically modifies a surface of the carbon nanotube with a plurality of polymers as in the conventional gas sensors is not needed, and the configuration can be simplified correspondingly.Type: GrantFiled: December 27, 2012Date of Patent: February 2, 2016Assignees: The University of Tokyo, Omron CorporationInventors: Isao Shimoyama, Kiyoshi Matsumoto, Yusuke Takei, Hidetoshi Takahashi, Noboru Kiga, Masahito Honda
