A flexible color-changing film inspired by chameleon
skin

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.
