This Color Changing Helmet Material Could Help Detect Concussions
A new helmet material that visually indicates how severe an impact is could help soldiers and athletes get quicker, better brain trauma diagnoses. The material, developed by a team of researchers at the University of Pennsylvania, changes color only when hit with a powerful, quick force. When hit with 30 millinewtons of force the material changes color from red to green. When struck with 90 millinewtons, it turns purple.
