Development of wireless bruxism monitoring device based on pressure-sensitive polymer composite

摘要

A wireless pressure sensing bite-guard has been developed for monitoring the progress of bruxism (teeth grinding during sleep); as well as protecting the teeth from damages. For sensing the pressure effectively in the restricted space and hostile environment, a pressure-sensitive polymer composite has been fabricated and encapsulated into a conventional bite-guard which is safe for in situ applications. The device is anticipated to give real-time data through wireless data transmission and to have a long working life (weeks). A microcontroller-based electronic circuit has been built in-house for data collection and transmission. A low power approach is configured to increase the working life of the device. This device is a useful tool for understanding and treating bruxism.
