Abstract

An electronic nose is a sensing array designed to monitor for targeted chemical species or mixtures. From 1995 to 2008, an electronic nose was developed at the Jet Propulsion Laboratory (JPL) to monitor the environment in human occupied spacecraft for the sudden release, such as leaks or spills, of targeted chemical species. The JPL ENose was taken through three generations of device, from basic exploratory research into polymer-carbon composite chemiresistive sensors to a fully operating instrument which was demonstrated on the International Space Station for several months. The Third Generation JPL ENose ran continuously in the U.S. Lab on the International Space Station to monitor for sudden releases of a targeted group of chemical species. It is capable of detecting, identifying and quantifying targeted species in the parts-per-million range in air, and of operating at a range of temperatures, humidities and pressures.
