Soldiers in battle wear many pounds of protective gear. But that protection isn’t perfect. Those who survive bomb blasts often suffer brain trauma, resulting in symptoms ranging from memory loss to blurred vision.But Shu Yang, a University of Pennsylvania materials engineer, has developed a crystal patch that changes color when hit by a shock wave. The resulting color can indicate the severity of the blast.
