The "electronic nose" is a relatively new tool that may be used for safety, quality, or process monitoring accomplishing in a few minutes procedures that may presently require days to complete. Electronic Nose is a smart instrument that is designed to detect and discriminate among complex odours using an array of sensors. The array of sensors consists of a number of broadly tuned (nonspecific) sensors that are treated with a variety of odoursensitive biological or chemical materials. An odour stimulus generates a haracteristic fingerprint from this array of sensors. Patterns or fingerprints from known odours are used to construct a database and train a pattern recognition system so that unknown odours can subsequently be classified and/or identified. Over the last decade, “electronic sensing” or “e-sensing” technologies have undergone important developments from a technical and commercial point of view. The expression “electronic sensing” refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems.For the last 15 years as of 2007, research has been conducted to develop technologies, commonly referred to as electronic noses, that could detect and recognize odors and flavors.
