New technique scales up production of graphene micro-supercapacitors

While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors. Engineers have now developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors. These micro-supercapacitors can be easily manufactured and integrated into small devices such as next-generation pacemakers.
