Abstract:
1. A device that comprises a high-strength structural capacitor that operates to store and release large amounts of electrical energy and that functions as a structural element in the device into which the high-strength structural capacitor is incorporated said high-strength structural capacitor comprising at least one pair of electrodes, said pair of electrodes comprising a positive electrode and a negative electrode; and a body of dielectric material disposed between said electrodes wherein the body of dielectric material accounts for a majority of the mass of the structural element or a majority of the volume of the structural element; wherein the combination consisting of said electrodes and said body of dielectric material has a stiffness of at least 10 MPa in a tension loading mode, in a compression loading mode, in a shear loading mode, in a bending loading mode and in a torsion loading mode further wherein said high-strength structural capacitor stores and releases energy at an energy density of at least about 0.1 J/cc.
