Robotic hand covered in 'electric skin' created

A robotic hand covered in'electric skin' that can harvest the sun's energy and feel touch better than a human has been developed by scientists. The electric skin is made from graphene - an ultra-thin form of carbon that is only an atom thick, but stronger than steel. The super flexible skin is hypersensitive to touch and may one day be used to make more responsive prosthetics for amputees, or to build robots with the sense of touch. Dr Ravinder Dahiya, pictured, from the University of Glasgow's School of Engineering, developed the hand which is covered in graphene Researchers incorporated photovoltaic cells into the electronic skin of the hand. Photovoltaic cells generate electricity by turning energy of the sun into a flow of electrons.
