Color-changing ‘blast badge’ developed

December 5, 2010

PHILADELPHIA, Nov. 29 (UPI) — U.S. researchers say they’ve developed a color-changing patch soldiers could wear on their uniforms to show the severity of their exposure to explosions.

University of Pennsylvania scientists say calibrating the color change to the intensity of the explosion could provide immediate information on possible injury to the brain and the need for medical intervention, a university release said.
