UK startup ORB Innovations is taking a new approach to collecting metrics by placing sensors into the mouths of athletes.
These sensors are housed in mouth guards and are mainly meant for contact sports, where one can’t wear a smartwatch. Along with a microprocessor, a Bluetooth module, and a battery, the ORB Smartguard can identify 20 different types of data—including heart rate, head impact, number of steps taken, and the overall movement of the person using it—by looking at changes in blood vessels in the mouth.
