Brain injuries are not always easy to detect early. We have already covered a bunch of wearable devices that catch head injuries quickly. Scientists are working on even more sophisticated technologies to address this issue. Professor Shu Yang and her team from the University of Pennsylvania have developed a polymer-based material that changes color depending on how hard it is hit. The goal is to incorporate this material into protective headgear to indicate brain injury.
