Impact-monitoring devices have increasingly popped up as knowledge of sports-related brain injuries become more common. Force Impact Technologies’
FitGuard has taken a different approach by monitoring from inside the mouth. The mouthguard is equipped with a Analog Devices ADXL377 accelerometer, a MAX21000 3-axis angular rate sensor, a TI CC2541 2.4 GHz Bluetooth Low Energy SoC, and a Seoul Semiconductor SFT825N-S RGB LED. Positioning inside the mouth gives sensors closer access to the brain, and LEDs turn on when a particular level of acceleration and impact is reached.
Coaches can monitor players with an app and flashing LEDs when a particular acceleration and impact is reached.

Force Impact hopes to build a database of impacts for a variety of sports in order to better understand what leads to injury. The mouth guards can be customized by a dentist and will be available in September for $100.
Mouthguards can be bought off-the-shelf or customized.
