The expression “electronic sensing” refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems. As electronics has already been extended to eyes,ears and now its turn for the Nose.
The electronic nose was developed in order to mimic human olfaction that functions as a non-separative mechanism: i.e. an odor / flavor is perceived as a global fingerprint. Essentially the instrument consists of head space sampling, sensor array, and pattern recognition modules, to generate signal pattern that are used for characterizing odors.
