Beyond Camouflage, Do You See Other Applications for Artificial ‘Chameleon Skin?’

A Cambridge University team developed an artificial "chameleon skin" that changes color when exposed to light. The material supports a range of applications, including active camouflage, large-scale dynamic displays, and maybe even medical diagnostics.

"Actually it was not something we really planned!" Dr. Andrew Salmon told Tech Briefs.
