Pressure and contact sensor system for measuring dental occlusion

Abstract From the Canadian patent

A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points. The sensor is especially useful for measuring dental occlusion The contact sensor includes two sets of parallel electrodes which are each formed on a thin flexible supporting sheet. The electrodes are separated by a thin, pressure-sensitive resistive coating such as molydenum disulphide. Two such electrode structures are oriented at approximately right angles to create a gride where the intersecting electrodes cross separated by the resistive coatings. Several arrangements of resistive coating over electrodes are disclosed. In the absence of an …
