An automatic electronic tongue system for classification of Indian wine

An automatic electronic tongue set up consisting of a robotic arm, potentiostat and rotary sample holder is developed in this work. The assembly mainly consists of a five motor robotic arm, a rotary sample holder platform having slots for placing sample to be investigated and a GAMRY potentiostat Interface 1000 A is used to perform cyclic voltammetry. The modelling of sample holder and robotic arm is done in CATIA software. The system uses an array of six working electrodes along with a reference and counter electrode to carry out cyclic voltammetry on three types of Indian wine. The generated data is then processed using Principal Component Analysis and Linear Discriminant Analysis classifier for classification purpose.
