South Korean scientists create chameleon-like artificial skin
Recommended for Secondary Grades
A team of South Korean scientists led by a man named Ko Seung-Hwan say that they have created chameleon-like artificial skin which changes its colour. They said that this artificial skin is thinner than human hair.
Chameleons are a family of lizards that are well known for being able to change the colour of their skin.
The scientists said that they have developed a special chameleon-like artificial skin that changes its colour according to its surroundings. They created the artificial skin with a special ink that changes its colour based on the surrounding temperature. And it is controlled by tiny heaters.
How does the chameleon-like artificial skin work?
Ko Seung-Hwan is a mechanical engineering professor. He said that the chameleon device is made up of thermochromic liquid crystal ink, vertical multilayer silver heaters and colour detecting sensors. Thermochromic paint or ink can change colour when exposed to a certain temperature.
First, the chameleon device detects the surrounding colours. Then, the collected information is transferred to the microprocessor and then into the silver nanowire heater. The heaters are then raised to a certain temperature. This change in heat helps the thermochromic liquid crystal layer in the skin to change its colour.
This chameleon-like artificial skin can be used as a wearable device and also for fashion purposes.
