Optoelectronic Camouflage Device Inspired by Marine Animals
Researchers from the University of Houston, University of Illinois at Urbana-Champaign, and Northwestern University have developed a technology that allows a material to automatically read its environment and adapt to mimic its surroundings. The optoelectronic camouflage system was inspired by the skins of cephalopods, a class of marine animals including squid and cuttlefish, which can change coloration quickly. The device reads the environment using thermochromatic material and has applications in defense and industry. The flexible skin of the device is comprised of ultrathin layers, combining semiconductor actuators, switching components, and light sensors with inorganic reflectors and organic color-changing materials in such a way to allow autonomous matching to background coloration.
