Chameleon fabric could lead to T-shirt monitors

When you hear "color-changing fabric," you probably think of those cheesy T-shirts from the '80s that turned a shade darker when worn by a warm body. Well, now we have the real deal: Dr. Greg Sotzing from the University Connecticut has created enhanced "electrochromic" polymers — a flexible material that changes color when an electrical charge is applied to it. Electrochromic polymers have been around for a while, but they were too small and fragile to be practical, but Sotzing has found a way to make them long and flexible enough to be woven into cloth. This potentially goes way beyond simply making your outfit that perfect shade of green; a jacket or shirt made from the polymers could actually serve as a TV screen for watching shows or serving up advertisements. Military camouflage would be enhanced as soldiers could adjust their fatigues to perfectly match their surroundings. The tech could even be used for flexible, roll-up monitors on things like cell phones and portable video players. It might feel weird dropping your cell phone off at the dry cleaner, though.
