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 Prototype sensor (top) and sensor response (bottom) to NO concentration in a simulate lean-burn exhaust conditions.

Sensor systems based on SRI technology could provide a low-cost alternative to current industrial emissions monitoring systems, as well as offer an inexpensive (approximately $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, GTI, and commercial clients.
