Superior Sensing Solutions proposed to design and develop inexpensive yet accurate sensors for the detection of CO in the presence of other reducing gases such as methane and hydrogen. The sensor will be based on the thermal effects due to catalytic oxidation of CO on nanoparticle derived metal oxide semiconductor surfaces. A thermopile will be used to sense the heat of combustion liberated. Catalyst and metal oxide composition, as well as operating temperature, will be manipulated to develop selectivity for individual species. PROPOSED COMMERCIAL APPLICATIONS: This technology has the potential of providing an intermediate product between low-performance, low cost solid state sensors and high performance/high cost EC sensors currently used for home CO detection.

Superior Sensing Solutions 建议设计和开发廉价但准确的传感器，用于在存在其他还原性气体（例如甲烷和氢气）的情况下检测 CO。该传感器将基于 CO 在纳米颗粒衍生的金属氧化物半导体表面上催化氧化产生的热效应。 热电堆将用于感测燃烧释放的热量。 催化剂和金属氧化物的组成以及操作温度将被控制以开发对单个物种的选择性。拟议的商业应用：该技术有潜力提供介于低性能、低成本固态传感器和目前用于家庭 CO 检测的高性能/高成本 EC 传感器之间的中间产品。
