| Outline of Final Research Achievements |
We developed a wearable mouth guard (MG) device with force sensors to monitor teeth clenching. The force sensor output increased linearly up to 70 N. In four simple occlusion tests (teeth clenching, teeth tapping, jaw movement, and teeth grinding), the trends exhibited by the outputs of the MG sensor were consistent with those of an electromyogram (EMG), and the MG device featured sufficient temporal resolution to measure the timing of teeth clenching. When the jaw moved, the MG sensor outputs depended on the sensor position. The MG sensor output from the teeth-grinding test agreed with the video-motion analysis results. It was comparatively difficult to use the EMG because it contained a significant noise level. The usefulness of the MG sensor was confirmed through an exercise tolerance test.
It indicated that the developed wearable MG device is useful for monitoring clenching timing and duration, and the degree of clenching during exercise,

| Academic Significance and Societal Importance of the Research Achievements |
運動時の咬みしめは、スポーツパフォーマンスや健康にとって重要である。口腔内の状態をモニタリングするためのマウスガード（MG）型ウェアラブルデバイスが研究されてきたが、新たに、開発したMG型ウェアラブルセンサは、咬みしめのタイミングや時間、運動中の咬みしめの強度をモニタリングするのに有用であった。
従来の筋電図活動（EMG）によるモニタリングに替わり、あるいは同時にモニタリングをすることで、運動時のスキルレベルに応じた咬みしめの傾向やタイミングなどを把握することでパフォーマンス向上の一助も期待される。
