Machine olfaction: Difference between revisions

'''Machine olfaction''' is the automated simulation of the [[olfaction|sense of smell]]. An emerging application in modern engineering, it involves the use of robots or other automated systems to analyze air-borne chemicals. Such an apparatus is often called an [[electronic nose]] or e-nose. The development of machine olfaction is complicated by the fact that e-nose devices to date have responded to a limited number of chemicals, whereas [[odor]]s are produced by unique sets of (potentially numerous) odorant compounds. The technology, though still in the early stages of development, promises many applications, such as:<ref>Sensors Council. (2012). Special issue on Machine Olfaction.
