Researchers develop color-changing fabric

A team of researchers at University of Central Florida has developed a fabric that changes color. The material uses thin metal micro-wires embedded with an electric current, which can change the wires’ temperature. Pigments within the thread respond to changes in temperature by changing color. The temperature shifts can be controlled through a user’s smartphone.

ChroMorphous technology is the first of its kind: an innovative textile that changes color and appearance on demand. Older versions of color-changing fabrics need sunlight or body heat to work, but none of them allow you to decide when and how the transformation will take place. An indoor/outdoor fabric, ChroMorphous surpasses the limitations of other color-changing clothing and textiles.

“Although clothing has been a staple of the human experience for millennia, the basic structure and functionality of textile fibers and yarns have remained unchanged throughout history,” said Ayman Abouraddy, a professor of optics and photonics at UCF, in a release. “The capabilities of electronics constantly increase and we always expect more from our iPhones so why haven’t textiles been updated?”

The mobile app that users can access with the fabric allows subtle changes in color or larger shifts. In an example provided by the researchers, a person could gradually add blue stripes to a tote bag by pressing a “stripe” button on the app. The team hopes to mass produce the technology, as they develop it to work with thinner threads.
