Rising fears about concussions in sports led to this product: a skullcap laden with sensors that can detect when an athlete has sustained a blow to the head and should come to the sidelines for an assessment. Such hits aren’t always seen by coaches and trainers. A yellow light comes on after a moderate hit; a red light indicates that the hit was severe. Football helmets with sensors already exist, but they cost more and aren’t widely used in youth programs. This product, which can be worn under a helmet or without one, could also be useful in hockey, soccer, and other sports where players fall or get knocked in the head.
