- Abstract
- In a previous report on a multicomponent sensor array for electronic tongues, carbon nanotube (CNT) composite sensors were identified as the most reproducible and sensitive. To further elucidate the response mechanisms and optimize the working parameters of CNT composite sensors, we focused on a single polymer CNT combination and tested its response to the 5 tastes in a variety of measurement modes. The results demonstrate that an acquisition frequency of 200 Hz is the most suitable in terms of concentration discrimination, and that this sensor was extremely sensitive to all tastes except sweet, indicating that the recognition is based on charge interactions between the sensor matrix and the analyte.
