Stretchy, Thermal 'Invisibility Cloak' Inspired by Squid Skin
To blend into their surroundings, cephalopods like cuttlefish and squid reflect light. Engineering professor Alon Gorodetsky and his team at the University of California-Irvine have developed a stretchy material, modeled after squid skin, that achieves thermal invisibility by reflecting heat. After being stretched or electrically triggered, the material’s thin swatches quickly change heat reflectance, smoothing or wrinkling their surfaces in under a second. This real-time infrared camera video clip is of the electrical actuation of a squid silhouette-shaped, aluminum-modified device.

Tech Briefs spoke with Alon Gorodetsky about the team's innovative, wrinkly material.
