Textile designer Judit Eszter Karpati creates color changing fabric

Although we haven’t yet figured out how to make a real invisibility cloak, we are coming up with better ways to camouflage ourselves. And what better way to do that than taking a cue from nature? The chameleon can change the color of its skin, so wouldn’t it be cool if we could to? Textile designer Judit Eszter Karpati may have found a way to do that, thanks to the use of an experimental fabric she created that changes color on the fly. Remember those t-shirts in the 1980’s that changed color with your body temperature? Those shirts used a conductive dye. Karpati’s material, Chromosonic, also uses conductive dye, but the rest of the color-changing process is much more high-tech: nichrome wires are woven into the fabric and connected to an Arduino microcontroller, which is connected to a power supply.
