  a team from the university of glasgow in the uk has come up with a version that harnesses the sun's rays. because it produces its own energy from a natural source, the engineers say, the electronic skin would operate longer than similar materials powered by batteries or tethered to a power source that would also limit portability, clearly a key feature of any everyday prosthetic or touch-sensitive robot on the go.
