Patent number: 10724979Abstract: Gas sensors are described herein that are useful for selectively detecting a second gas (e.g. isoprene) in the presence of a first gas (e.g. acetone). The gas sensors include a sensor element which includes a semiconductor sensing material and a porous material. The sensor element is configured so that the porous material absorbs more of the first gas than the second gas. Thus, when the gas being analyzed, such as a mammalian (including human) breath, a greater proportion of the second gas comes into contact with the semiconductor sensing material.Type: GrantFiled: May 25, 2016Date of Patent: July 28, 2020Assignee: Nitto Denko CorporationInventor: Qianxi Lai
