The team of researchers of the University of Glasgow, led by Dr. Ravincer Dahia, developed electronic skin based on graphene with increased sensitivity and the ability to generate energy from the sun. It can find application when creating “sensitive” prostheses and robots with a touch.
Graphene – almost perfect material for collecting solar energy and converting it into electrical. So far, the energy produced by the skin cannot be preserved, but scientists are looking for the opportunity to “store” energy in batteries to use it when the need arises.
According to Dr. Dahia, human skin was a guideline, which is a complex biological system that responds to changes in temperature and pressure.
The team has already achieved success in creating prototypes of prostheses with sensitive synthetic skin. Such prostheses can perform complex tasks, for example, interact with soft materials, which is not available to other artificial manipulators.
Experimental prostheses can already reproduce many mechanical movements characteristic of human limbs, and in combination with sensitive skin, their capabilities increase many times.
Artificial leather consumes only 20 Nanovatt per square centimeter, about the same as an affordable photo transformers of medium quality.
The next step, according to Ravincer Dahia, will be the opportunity to use the resulting energy to drive a hand in motion, and then the creation of a completely autonomous prosthesis.
