Robot skin inspired by chameleon will instantly change color


“[Building] The first prototype is very slow,” Hwan Ko said. The first step is to determine whether the robot imitates a vertebrate-an animal with a spine-or an invertebrate, such as a squid or an octopus. Because invertebrate models can provide more The team initially planned to imitate the octopus, but Hwan Ko said the idea proved to be “too ambitious”.

After fiddling with different designs and material structures, the team finally decided to solve the simpler form of the chameleon itself. By shaping the nanowires into simple patterns consisting of dots, lines, or scale shapes, they were able to create the complex effects shown in this video.

although Previous research on artificial camouflage Hwan Ko is often labeled for military use, hoping that their work will have a wider impact, especially in the fields of transportation, beauty and fashion. Future applications may include cars that change colors to make them stand out, or even color-changing cloth.

“The skin of this chameleon, on the surface, is basically a display,” he said. “It can be used for soft, stretchable or flexible displays.”

However, because the technology relies on temperature, it does not work well in extreme cold conditions, which makes it more difficult for artificial chameleons to achieve full-spectrum colors.

Ramses Martinez An assistant professor at Purdue University who also studies bionic robotics said that converting other bionic-inspired systems into new technologies may bring more possibilities, including systems that help locate survivors after earthquakes.
