Project Description

This project aims at developing a wireless integrated gas/temperature microwave acoustic sensor capable of passive operation (no batteries) over the range 350 degrees Celsius (°C) to 1,000 °C in harsh environments relevant to fossil energy technology, with specific applications to coal gasifiers, combustion turbines, solid oxide fuel cells, and advanced boiler systems. The proposed wireless sensor system is based on a surface-acoustic-wave sensor platform that is configured using a langasite piezoelectric crystal with Pt/Pd interdigital electrodes and yttria-stabilized zirconia films doped with Pd, Pt, or Au nano-catalysts to detect H2, O2, and NOx gases and to also monitor the gas temperature in the harsh environment. Fully packaged prototype sensors will be designed, fabricated, and tested under gas flows of H2 (< 5 percent), O2, and NOx in laboratory furnaces, and the sensor response will be characterized for sensitivity, reproducibility, response time, and reversibility over a range of gas temperatures.

Project Benefits

This project could advance development of high temperature stable sensing materials by developing a novel high temperature sensing strategy to realize fast, sensitive, selective, rugged, and cost-effective high-temperature gas sensors for power and fuel systems. The sensing technique developed could be suitable for various fossil energy end-use applications ranging from ultra-supercritical boilers (up to 760°C) to solid oxide fuel cells (650-1000°C) and automotive engines (up to 1000°C).
