This image obtained August 19, 2014 courtesy of John Rogers/Department of Materials Science and Engineering, University of Illinois shows an adaptive camouflage in operation. A study finds that a temperature-sensitive dye coupled with a distributed array of photosensors on a thin flexible electronic substrate can yield systems capable of automatically adapting to match the coloration of their surroundings as a bio-inspired camouflage. Mimicking the adaptive camouflage systems of cephalopods presents various technical challenges. John A. Rogers and colleagues took inspiration from cellular mechanisms found in cephalopods to design and construct such a system. The top layer is composed of a temperature-sensitive dye that appears black at low temperatures and clear at temperatures above 47° C, overlaying a white reflective layer of silver and an ultrathin silicon diode to modulate the dye’s temperature.
