Development of an electronic tongue based on potentiometric sensors

摘要

In the frame of a joint research between the University of Rome "Tor Vergata" (Sensors and Microsystems group), and the Laboratories of Chemical Sensors of the University of St. Petersburg, an Electronic Tongue has been designed, constructed and applied to qualitative analysis of different kinds of complex liquids, such as mineral waters, wines and biological samples. The results presented in this paper show that the electronic tongue can give interesting information in various applications of fundamental interest (i.e. drinkable water control, food industry and medicine).
