最近，由于食物的软化，我们的咀嚼次数下降了。这对我们的健康和脑细胞的发育有影响，特别是对儿童。应牙医的要求，我们开发了一种咀嚼次数计数设备，可以像计步器一样方便地使用。该设备使用带有半导体压力传感器的头带检测颞肌的微小扩张。实际使用后，澄清了孩子们需要一些时间才能将设备固定在正确的位置，有些人不想在吃饭时间固定头带。在本文中，为了解决上述问题，我们提出了一种新型的咀嚼计数设备，使用红外传感器连接在一个人的眼镜腿。该装置无需接触头部即可检测咀嚼次数，并可通过改变传感器负载电阻进行调整。结果表明，该系统的计数精度为4.6%，误差小于1.5%。
Recently our chewing number is declined to decrease owing to softening of foodstuffs. That has influence on our health and development of brain cells,especially for children. Receiving the request of a dentist, we developed a chewing number counting equipment that can be used with the easiness like a pedometer. That equipment detects the small expansion of the temporal muscle using a head band with a semiconductor pressure sensor. After practical uses, it was clarified that it has some time for children to attach the equipment at the correct place and some people don't want to attach the head band in their meal time. In this paper, for solving the problems mentioned above, we propose a new type chewing number counting equipment that uses an infrared sensor attached at the temple of one's glasses. The proposed equipment can detect the chewing number without touching one's head and be easily adjusted by changing a sensor load resistor. As a result, we could get the counting accuracy with 4.6% errors.
