A New Way to Detect Traumatic Brain Injury

A New Way to Detect Traumatic Brain Injury


​I’m Gabe Garza with today’s health news.
​At the time of impact, there is no easy way to tell if someone has sustained a brain
injury. But a novel new tool may soon change all that. Researchers from the University
of Pennsylvania have created a polymer that changes color depending on how hard it is
hit. Incorporated into a helmet, a patch of this polymer might be able to alert the wearer
or observers of a brain injury. Researchers created crystals that contain particular colors.
When the crystals are damaged by a hit, they become deformed and change in color. The team
is currently working on ways to decrease the cost of the materials and make this polymer
commercially available for protective headgear.
