Graphene supercapacitors use the sun to power advanced wearables
researchers at the University of Glasgow are using graphene to create next-generation flexible batteries — more accurately, supercapacitors — that are capable of recharging using solar energy, as well as discharging enough energy to power advanced wearable devices.
The full report is available, and is certainly worth reading if you’re interested in how portable and wearable devices will be powered in the foreseeable future
