A flexible color-changing film inspired by chameleon skin (video)

Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.
