The history of development of "electronic tongue" multisensor systems whose operation is underlain by principles close to those in biological sensory systems was briefly overviewed. The main types of "electronic tongue" systems developed by now were described, along with sensor materials and sensors applied in such systems. The most widespread applications of "electronic tongues" were discussed including those for recognition and classification of liquid media, quantitative analysis of various components in these liquids, smart monitoring of industrial processes, and evaluation of the type and intensity of the flavor of various foodstuffs and drugs.
