Biocompatible Supercapacitor Using a novel microfabrication approach based on anodic aluminum oxide templates, Guoguang Rong, Mohamad Sawan, and co-workers fabricate a biocompatible supercapacitor in article number 2100608, with a large capacitance value, as well as good transparency, stretchability, and biocompatibility. This supercapacitor is intended to be used as a power source for flexible printed circuit to stimulate the brain's neural tissues.
