Claim 0:
1. A stretchable supercapacitor comprising:
first and second electrodes spaced apart on a substrate comprising an elastomeric polymer, wherein at least one of the first and second electrodes comprises a carbon-metal oxide composite electrode having a composite structure including carbon nanotubes and a metal oxide comprising manganese oxide, the metal oxide being uniformly dispersed within the composite structure;
a gel electrolyte applied over the first and second electrodes and the substrate, the gel electrolyte comprising polyvinyl alcohol (PVA); and
an operating voltage window in a range from 1.2 V to 1.8 V,
wherein the first and second electrodes have a buckled structure formed upon release of tensile strain in the substrate during fabrication.
