Helmets can change their color depending on the head injury level [video]


If you are a football/ hockey or any-other-sport-that-implies-your-head-being-crushed player, maybe you know that unless you see some blood, a serious head injury might be easily forgotten if you are still capable of carrying on the game.


In order for this danger of underestimating a head injury, some scientists from University of Pennsylvania have created a special polymer that changes color depending on the intensity of the force applied to your head, indicating if it is possible for you to suffer a trauma.


This way, with the help of some photonic crystals that change their color structure when they deform after a kick, every helmet can me modified in this sense, without bringing any change in form or weight. check out the video below.
