Abstract
Abstract A flexible, multilayer thin film capacitor comprises a flexible substrate and at least two electrode layers mounted on the substrate alternately with at least one dielectric layer. The dielectric layer may include amorphous hydrogenated carbon. The at least two electrode layers and the at least one dielectric layer are capable of acting as at least one capacitor, and the flexible substrate is capable of being manipulated so as to have a desired shape.
