To date, our research group has been developing a CMOS potential-detection-type odor sensor in which multiple odor-sensitive films are selectively deposited on a potential sensor array, and we have successfully achieved the discrimination of multiple gases. However, although this sensor is known to exhibit two types of response, it is difficult to detect them separately. Therefore, in this study, we proposed a measurement method capable of separating these responses, and designed and fabricated the sensor. In this presentation, we report on the verification of the proposed method’s principles.
