Beijing, Jul 26 (PTI) Scientists have developed a user- interactive colour changing electronic skin inspired by chameleons that could be used in robotics, prosthetics and wearables. While science has been able to replicate the ability of animals such as chameleons, octopus and squids to change colour with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain. Now, researchers from Tsinghua University in China have developed a new type of user-interactive electronic skin, with a colour change perceptible to the human eye, and achieved it with a much-reduced level of strain. "We found subtle strain - between zero and 10 per cent - was enough to cause an obvious colour change, and the RGB (red green blue) value of the colour quantified the magnitude of the applied strain," said Tingting Yang from Tsinghua University. "Its important to note that the capability we found for interactive colour changes with such a small strain range has been rarely reported before.
