Artifical Chameleon Skin Triggered by Heat

Aug-29-19 A color-changing material triggered by heat could have applications ranging from active camouflage to large, dynamic displays.

The material was developed by a team from the University of Cambridge, who were inspired by the color-changing skin of animals like the chameleon and cuttlefish—in particular, the animals’ specialized skin cells called chromatophores. The researchers created their artificial version of the cells using tiny gold particles that were coated with a polymer shell and then squeezed into microdroplets of water in oil. Heating or cooling the material will cause the nanoparticles to contract or expand, altering the shape of the particle clusters and resulting in ‘dramatic color changes.’
