In-situ, real-time monitoring the composition of combustion gases usually requires sensors to be operative at high temperature environment. Up to date, commercially available sensor technology for such harsh environment is extremely limited due to the high requirements for sensing materials and sensor performance. Therefore, there is an urgent need to advance high temperature stable sensing materials and develop novel high temperature sensing strategy to realize fast, sensitive, selective, rugged, and cost-effective high-temperature gas sensors for power and fuel systems. This talk will first discuss nanomaterials enabled high-performance resistor-type gas sensors, which have been extensively studied for high temperature environment in our group, followed by the discussion of its current challenges. Finally, we will discuss our recent work on exploring the strategy such as passive SAW sensor to improve the high temperature gas sensing wireless capability.
