　　A study found that the combination of a temperature-sensitive dye and a distributed light sensor on a thin flexible electrical substrate can bring about a system capable of automatically adapting to match the colors of their surroundings, as a biological slave Disguise for inspiration.

　　There are many technical challenges in passive camouflage systems that mimic cephalopods. John A. Rogers and colleagues took inspiration from the cellular mechanisms discovered in cephalopods to design and construct such a system.

　　The top layer of is composed of a photosensitive dye that is black at low temperatures and is transparent over 47 degrees Celsius. It is covered with a silver white reflective layer and an ultra-thin silicon diode to adjust the color of this dye. A base layer contains distributed, multiplexed light detectors that provide functions similar to the light-sensitive opsin in cephalopod cells. This passive camouflage system arranged in an array of flexible units reacts to various changing patterns of lighting within 1-2 seconds without requiring user input.

　　The authors say that these results suggest that these technologies and the operating principles of this system may lead to fully adjustable, full-spectrum adaptive camouflage integrated into scalable electronic devices, with commercial, military and industrial uses.
