Smart mouth guard controls electronic devices by biting – IoT World Today

The new interactive mouthguard allows users with limited or no hand mobility to control nearby electronic devices by biting down on the device.

The design comes from the National University of Singapore (NUS) together associates from Tsinghua University. The bite-controlled pressure sensor system was developed to provide an alternative to existing assistive technologies, including voice recognition and eye tracking, which have some limitations due to environmental influences and inaccuracies.

According to the team, the bite technology has an accuracy rating of 98%, and the system allows users to control devices such as smartphones, computers and electric wheelchairs.

“We also demonstrated that our new sensors can distinguish between mechanical deformations, including tension, compression and bending, making them applicable to multi-purpose mechanical sensing applications,” said Professor Liu Xiaogang, the research leader. “[This includes] miniature force sensor, flexible electronics, artificial skin and dental diagnostics.”

The team first designed a sensor consisting of a series of contact pads that light up when pressure is applied and placed inside a flexible mouth guard. Data collected from different bite patterns on these sensors was then used to remotely control various devices

The team’s study was published in the journal “Nature Electronics” and a patent was issued for the technology. Further investigation into testing mouthguards in clinical settings, as well as speeding up data processing and training times, is underway.
