| Abstract: | A novel voltammetiy electronic tongue, smart tongue based on virtual instrument was developed. The instrument consisted of a particular electrochemical sensor array module, a self-designed signal conditioning module, a data acquisition card and a developed software tool, Lab VIEW programming. The system implemented main performances as follow, generating excitation signal, acquiring and displaying multi-channel signal, extracting characteristic numbers, sharing samples database. Five Mas-terkong tea beverages were detected. Then the principal component analysis was used for processing data. The results show that the proposed equipment has good discrimination ability. It proves that the design of smart tongue based on virtual instrument technology is feasible. |
