It is the first time microfluidics is applied in e-tongue devices. A detailed work has being done to verify the best conditions involved in the microchannel fabrication, their integration with interdigitated electrodes (IDEs) and further recover of the IDEs with ultrathin films for signal acquisition. This integration becomes an important key to the development of a new technology with strong commercial appeal, besides the volume reduction in the analysis, minimizing chemical waste and a decrease in the time of analysis, as data acquisition is get in flow measurements.
