Developments in Electronic Nose Systems

Electronic nose has received considerable attention of the research scholars and industries because of its wide range of applications and the innovations done in the field of sensor technology. E-nose technology has quietly advanced during the last twenty years. Commercial models equipped with sensor arrays came to market in the mid-1990s, and today they're being used in every aspects of our life e.g. food, health, pharmaceuticals, environment monitoring, manufacturing, cosmetics, and packaging industries etc. In this paper we have discussed some of the research works and the developments done in electronic nose systems during last few years.
