Researchers at the National Institute of Standards and Technology (NIST) claim its electronic nose can identify hundreds of different chemical compounds using pattern-recognition algorithms that mimic the way animals recognize odors. NIST's electronic nose depends on 16 microheater elements supplying samples to eight different types of sensors, enabling them to detect everything from nerve gas to environmental contaminants. NIST researchers suggested the microheater technology could be used in handheld devices used by first responders and hazardous material teams as well as for industrial processes monitoring and space exploration.
