Chemical Sensors

SRI has developed the electrode materials that have the necessary selectivity to make automotive type oxygen sensors selectively measure NO in exhaust gas. We are currently fabricating and testing emissions sensors using these materials. Our sensor technology is multifunctional because it can simultaneously measure both NO and O₂.

Sensor systems based on our technology could provide a low cost alternative to current industrial emissions monitoring systems as well as an inexpensive ($15/unit), rugged, solid-state device capable of meeting the automotive OBD regulations. There is currently a large market for these types of gas sensors, and demand is expected to increase significantly in the near future because of state and federal mandates for better monitoring and lower emissions. SRI's research in chemical sensors is supported by EPRI, GRI, and commercial clients.
