Abstract: A capacitor assembly includes a capacitor having ends. A terminal covers less than an area of one end. A wire bond has opposing ends with one end being coupled to the terminal and is configured to break connection with a circuit when an electrical current through the wire bond reaches a fusing current. An energy storage module includes at least two capacitor assemblies. The wire bond of one capacitor is electrically connected to the second terminal of an adjacent capacitor. An energy storage assembly includes two energy storage modules stacked one on top of the other. A pulse forming network includes conductors and at least two energy storage modules. A method of making a module includes charging each of the capacitors, removing each capacitor that fails, connecting one end of a wire bond to one terminal and connecting the other end to an adjacent capacitor or to a conductor.

Abstract: A method for using a graphene field-effect transistor (GFET) as a reconfigurable circuit, the method comprising the following steps: depositing a liquid dielectric over a graphene channel of the GFET; applying an activation energy via a first electric field across the liquid dielectric and the graphene channel to electrochemically produce chemical species within the liquid dielectric such that the chemical species accumulate at, and molecularly bond with, the graphene channel thereby decreasing a conductivity of the graphene channel; and applying a deactivation energy via a second electric field of opposite polarity to the first electric field to remove interaction between the chemical species and the graphene channel to increase the conductivity of the graphene channel.

Abstract: An energy storage device comprises a capacitor having a dielectric between opposite electrodes and a nonconductive coating between at least one electrode and the dielectric. The nonconductive coating allows for much higher voltages to be employed than in traditional EDLCs, which significantly increases energy stored in the capacitor. Viscosity of the dielectric material may be increased or decreased in a controlled manner, such as in response to an applied external stimulus, to control discharge and storage for extended periods of time.
