Scientists create new synthetic ‘chameleon skin’ that changes color on demand

Taking a cue from a certain color-shifting lizard, researchers at the University of California at Berkeley have created a new super-thin material that can change color on demand. The new technology could open up a new world of display possibilities, from adaptable military vehicle camouflage to brilliant color presentations for outdoor venues. “Although we are still in the early stage of process/fabrication development,” study author and team leader Professor Connie J. Chang-Hasnain said, “I am optimistic that some form of this technology should reach the public domain soon.”

The material is made by etching tiny ribbons onto a layer of silicon (a thousand times thinner than a human hair) within a flexible sheet of film, and can change colors simply by being flexed or bent. The team has worked with silicon ribbons since 2003, but it was only 9 months ago when they decided...
