As prosthetics grow ever more advanced — some now with a motorized function capable of grasping, pointing and even holding objects — one question remains: how will these futuristic limbs, which rely on considerable energy, be powered?
A Wearable Supercapacitor
Engineers at the University of Glasgow believe they have created a solution: a kind of electronic skin made from graphene, polyurethane and graphite that can generate and store solar energy for prosthetic devices.
A thin layer of graphene acts as a solar converter, converting sunlight to electrical energy. The polyurethane-graphite composite sits below the graphene, acting as a supercapacitor that...Electronics, Innovation Bonds
