　　According to a study, the combination of temperature-sensitive dyes and distributed light sensors on a thin and flexible electronic substrate can automatically adapt to the surrounding colors, and as a living being inspired by camouflage. You can bring a system that works.

　　There are many technical challenges in the passive camouflage system that mimics cephalopods. Inspired by the cell mechanism of cephalopods, John A.ogers and his colleagues designed and constructed such a system.

　　The top layer is composed of a photosensitive dye that is black at low temperature and transparent above 47 degrees Celsius, and is covered with a silver white reflective layer and ultra-thin silicon diode to adjust the color of this dye. The base layer contains a decentralized multiplexed photodetector that provides a function similar to the light-sensitive opsin in cephalopod cells. This passive camouflage system is located in a series of flexible units that can respond to a variety of changing lighting patterns within a second or two without user input.

　　Author, these results may lead to a fully adjustable full-spectrum adaptive camouflage, where these technologies and the operating principles of the system are integrated into scalable electronic devices for commercial, military, and industrial applications.
