Project Description

Researchers at West Virginia University (WVU) will develop micro-scale, chemical sensors and sensor arrays composed of nano-derived, metal-oxide composite materials to detect H2 and H2S within high-temperature environments (500-1200ºC). Most micro-patterned semi-conductor based chemical sensors use thin film deposition and wet/dry etching processes. This work will demonstrate an innovative microcasting process for forming chemi-resistive sensors with 20-100 µm feature size of various geometries composed of nano-composite electrodes that display high-temperature microstructural and morphological stability. In order to achieve this goal, the work will concurrently address issues relating to electrode stability, selectivity, and sensor miniaturization.

Project Benefits

This project will develop micro-scale chemical sensors and sensor arrays to detect gases such as H2 and H2S within high-temperature environments, represnting the next step in monitoring and control technology. The overall impact of this technology will be lower operating costs by allowing more accurate measurement of the conditions inside a gasifier or boiler to better control their operation.
