Chinese researchers have developed a user-interactive electronic skin that can change colour — an ability associated with animals such as chameleons, octopuses and squid. The changes are perceptible to the human eye without much strain. Though science has been able to replicate these abilities with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain.
The research conducted by Tsinghua University in Beijing can have applications in robotics, prosthetics and wearable technology. “This user-interactive e-skin should be promising for applications in wearable devices, robots and prosthetics in the future,” the study mentioned. The researchers employed flexible electronics made from graphene, in the form of a highly-sensitive resistive strain sensor, combined with a stretchable organic electrochromic device.
