  • Publication number: 20150206660
    Abstract: A capacitor includes a pair of electrodes and a metalized dielectric layer disposed between the pair of electrodes, in which the metalized dielectric layer has a plurality of metal aggregates distributed within a dielectric material. The distribution is such that a volume fraction of metal in the metalized dielectric layer is at least about 30%. Meanwhile, the plurality of metal aggregates are separated from one another by the dielectric material. A method for forming a metal-dielectric composite may include coating a plurality of dielectric particles with a metal to form a plurality of metal-coated dielectric particles and sintering the plurality of metal-coated dielectric particles at a temperature of at least about 750° C. to about 950° C. to transform the metal coatings into discrete, separated metal aggregates.

  • Publication number: 20140233153
    Abstract: A capacitor, and methods of its manufacture, having improved capacitance efficiency which results from increasing the effective area of an electrode surface are disclosed. An improved “three-dimensional” capacitor may be constructed with electrode layers having three-dimensional aspects at the point of interface with a dielectric such that portions of the electrode extend into the dielectric layer. Advantageously, embodiments of a three-dimensional capacitor drastically reduce the space footprint that is required in a circuit to accommodate the capacitor, when compared to current capacitor designs. Increased capacitance density may be realized without using high k (high constant) dielectric materials, additional “electrode—dielectric—electrode” arrangements in an ever increasing stack, or serially stringing together multiple capacitors.

  • Patent number: 8441156
    Abstract: An electrically conductive module is provided. The module includes a panel configured to engage with one or more conductive structural elements. The module further includes conductive layers formed on or in the panel. Each conductive layer has a terminal configured to be in electrical communication with at least one of the conductive structural elements. In one embodiment of the present invention, a first terminal is configured to be in electrical communication with a first conductive structural element and a second terminal is configured to be in electrical communication with a second conductive structural element. In another embodiment of the present invention, both a first terminal and a second terminal are configured to be in electrical communication with a first conductive structural element. In this embodiment, the first and second terminals are respectively configured to be in electrical communication with first and second conductive portions of the first conductive structural element.
