Electronic nose olfactory. 3399 Artificial Olfaction The electronic nose or e-nose is an artificial sensing system that typically uses an array of different sensors followed by pattern recognition. The olfactory receptors are employed as a biological element in this type of instruments. There are currently two major applications for this type of sensor.

In animals and humans smells produce a response in olfactory cells in the nose which send signals to the brains olfactory system where electrical pulses within an interconnected group of neurons generate a sensation. The electronic nose e-nose comprises a barcode that changes color over time in reaction to the gasses produced by meat as it decays and a barcode reader. Signal processing inspired from the olfactory bulb for electronic noses To cite this article.

To classify odours the human olfactory system uses hundreds of different olfactory receptors and a specialized neural architecture.
