Artificial skin that changes colours like a chameleon created by South Korean scientists

Researchers in a lab in the South Korean capital Seoul have created a chameleon robot that instantly changes its skin colour to match its surroundings. The team at Seoul National University developed their camouflage technology using special ink that changes colour based on temperature, controlling the changes with an extremely thin and flexible layer of heaters. Demonstrating the device on September 7, 2021, lead researcher Ko Seung-hwan said an immediate goal for the project is to develop clothing such as military uniforms that can actively change colours and patterns to offer more effective camouflage.
