Revolutionary Football Helmet Technology

New football helmet technology could make it safer for your child to play the game.

An engineering student at BYU has invented a "smart foam" that tracks the hits players take to the head.

Jake Merrell invented "XOnano foam" by inserting extremely small nanoparticles into the foam in football helmets. When the foam is compressed it generates a tiny voltage. That signal is then sent wirelessly to a tablet on the sidelines.

That information allows coaches to know the acceleration and force of each hit in real time, so they can decide if a player needs to sit out, or if they can still play.

The new technology comes at a time when there are several studies on the long term effects of concussions in football players.

Merrell hopes the helmets are ready to use by BYU's spring practice. He eventually wants to expand so all levels of football, from peewee to the NFL, can use them.
