Newly developed robotic skin is more sensitive than human skin

A team of researchers at University of Glasgow claimed to have developed an electronic, self-powered robotic hand that is more sensitive to touch than a human hand.

Prof. Ravinder Dahiya, an electrical engineer at the university, explained that the new robotic skin is made of a single atomic layer of graphene, and is essentially a touch sensor.

It requires just 20 nanowatts of power per square centimeter to operate, and the researchers turned to the Sun for that. Under the surface of the graphene skin, there is a solar panel that absorbs sunlight and turns it into power.

Speaking on the topic, Prof. Dahiya said, “Whatever light is available, 98 percent is going and hitting the solar cell … it is generating power that can be used to get the sensitivity, the tactile feeling.”

Prof. Dahiya added that the robotic graphene skin equipped with first-of-its-kind sensor is one order of magnitude better than humans’ skin.

The research is being seen as a step towards development of more lightweight prosthetic limbs for humans, as well as more robots covered in human-like soft skin.
