London, August 9 : Japanese researchers have proposed an idea to use stretchy circuits made from rubber and nanotubes to create an “e-skin”, which will be flexible enough to completely cover a robot without limiting its movement.
"Without human skin-like sensitivity, robots cannot be used in everyday life. Imagine the danger if a robot did not recognise when it had accidentally bumped into a young child," New Scientist magazine quoted Takao Someya of the University of Tokyo as saying.
He has already developed a rubbery conductor, that can be stretched by 38 per cent without any drop in its conductivity.
He says that a net of it was still working after being stretched by 134 per cent, though with a drop in conductivity.
