A sensor-enabled mouth guard able to detect when a person is grinding their teeth could also have applications in monitoring hydration levels and concussions.
Created by a team of engineers from the University of Florida, the smart mouth guard is equipped with sensors able to detect the motions of grinding teeth. The information is then transmitted via Bluetooth to a computer or smartphone, where it can be retrieved by a dentist for study or treatment recommendations. Typically, diagnosing teeth-grinding requires a trip to a sleep clinic, since most people are not even aware they are doing it.
With a few alterations, the smart mouth guard could also be used to detect hydration, core temperature, or the possibility of a concussion.
