ABSTRACT
We propose a number-of-chewing measuring device which detects upheaval of a temporal muscle using the flexible capacitive sensor. We focused on the feature of the temporal muscle which swells up during chewing action. It is possible to distinguishing the chewing action from the conversation accurately. An advantage of our technique is that the device can be installed readily only by fixing the sensor with the head belt. Furthermore, since the sensor is has a wide flexible sensing area, fine adjustment of the sensor location in not necessary. Moreover, the threshold adjustment at each installation is unnecessary with an automatic gain control function of the sensor. Experimental results revealed the applicability.
