A team of Korean researchers has just developed a chameleon robot wrapped in a membrane that changes color to mimic its environment. This technology could have applications even in architecture and fashion.
Chameleons manage to changethanks to the contraction of muscles under the skin, which act on nanocrystals. Researchers had already succeeded in creating with a similar ability, which reacts when bent or stretched. However, the Korean team opted for another track, using the .

A change of color thanks to the heat
Scientists have created a soft robot with a “skin” made up of a layer of crystals. Below it, they placed a structure made up of several layers of which serve as heating elements. This structure allows the robot not only to change color, but also to create patterns to better blend into the decor.
The robot is equipped withto detect the colors of its environment connected to a microcontroller which translates the color into temperature and allows the robot to change color in real time. The robot is not yet able to generate patterns automatically, but this is one of the next goals. Ultimately, researchers imagine applications not only for military camouflage, but also in the field of architecture, art and fashion.
