There is a demand to know occlusal wear. To meet this demand, we have developed a sensor system and successfully detected the tooth occlusal force and relative position between upper and lower tooth. The force sensor was fabricated by using silicon micromachining. The position sensor consists of a micro-inductor and three individual coils, and magnetic coupling effect between them was utilized to determine the relative positions of the facing upper and lower teeth. These sensors were built in the artificial teeth.
