We have seen a few novel approaches to tackling the issue of concussion in sport recently. These have included football helmets that flex like car bumpers, sideline systems that diagnose concussion in a minute by tracking eye movements and neck bands that help soften blows to the head.
Samsung's prototype device also comes in the form of a discreet band, though it is meant to be worn around the noggin like a regular sweatband. It has sensors embedded at the back of the head to measure the force of an impact, with data able to be sent to medics, referees and coaches in real-time via a companion app.
