Abstract In this work we report on a new type of pressure sensor and its application to palatography. The device is a flexible sheet sensitive to pressure-induced changes in capacitance with a spatial resolution of 2 mm. When mounted to a plastic palatal plate thermoformed off a subject’s dental cast we have used it to record lingual palatall contact pressure from 25 distributed locations at a 40Hz/sensor sampling rate. Because of pervasive noise and problems with calibration our results obtained using the device are preliminary, though consistent with previous work in this area.
