Color-Changing ‘Blast Badge’ for TBI

“U.S. researchers say they’ve developed a color-changing patch troops 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.
‘We wanted to create a ‘blast badge’ that would be lightweight, durable, power-free, and perhaps most important, could be easily interpreted, even on the battlefield,’ Douglas H. Smith, professor of neurosurgery at Penn State, said.
Blast-induced traumatic brain injury has been described as the ‘signature wound’ of the current wars in Iraq and Afghanistan.”
