A Brigham Young University student has developed a nano particle-embedded foam that can detect and measure impacts. This will accurately help diagnose player concussions in the middle of a game. It can provide real time feedback about the severity of a hit or tackle.

Jake Merrell's foam looks and acts like the soft material used in helmets but also produces an electrical current that can be instantly measured. Coaches, trainers and medical personnel on the sides will have instant feedback on how hard a player was hit and whether there could be a possibility of a concussion.
