What this “intelligent mouthguard” does is that it records the g-force of collisions between players during the course of the game through the use of acceleration and rotation sensors, which gather real-time in-game data and send it via wireless transmitter to a laptop along the sidelines. The information collected will then be used by medical experts and designers of protective gear to help design gear which will better protect the player.
The mouthguards will be put to the test during the end-season game between Notre Dame and Stanford, with the Stanford players also sporting the mouthguards which should be providing a goldmine of data for the researchers.
