  • Patent number: 7847669
    Abstract: Disclosed is an integrated tunable inductor having mutual micromachined inductances fabricated in close proximity to a tunable inductor that is switched in and out by micromechanical ohmic switches to change the inductance of the integrated tunable inductor. To achieve a large tuning range and high quality factor, silver is preferably used as the structural material to co-fabricate the inductors and micromachined switches, and silicon is selectively removed from the backside of the substrate. Using this method, exemplary tuning of 47% at 6 GHz is achievable for a 1.1 nH silver inductor fabricated on a low-loss polymer membrane. The effect of the quality factor on the tuning characteristic of the integrated inductor is evaluated by comparing the measured result of substantially identical inductors fabricated on various substrates. To maintain the quality factor of the silver inductor, the device may be encapsulated using a low-cost wafer-level polymer packaging technique.

  • Publication number: 20100028736
    Abstract: A membrane electrode assembly for use in a fuel cell includes an anode electrode, a cation exchange membrane, an anion exchange membrane and a cathode electrode. The anode electrode includes a first catalyst. The first catalyst separates a reducing agent into a plurality of positively charged ions and negative charges. The cation exchange membrane is configured to favor transport of positively charged ions therethrough and is also configured to inhibit transport of negatively charged particles therethrough. The anion exchange membrane is configured to favor transport of negatively charged ions therethrough and is also configured to inhibit transport of positively charged ions therethrough. The cathode electrode includes a second catalyst and is disposed adjacent to a second side of the anion exchange membrane. The second catalyst reacts electrons with the at least one oxidizing agent so as to create reduced species.

  • Publication number: 20090142648
    Abstract: The present disclosure relates to a glass composite catalyst electrode comprising a glass matrix and metal particles incorporated into the glass matrix. The present disclosure also relates to a method for composing a glass composite catalyst electrode. A glass composite catalyst electrode is a porous homogeneous structure with an approximately uniform distribution of metal particles. The metal particles are operable to catalyze reactions in the fuel cell. Conductive material, which may also be operable to catalyze reactions in the fuel cell, may be deposited on the glass composite catalyst electrode in order to increase the electrical conductivity of the glass composite catalyst electrode and to increase the electrochemically active area of the glass composite catalyst electrode.

  • Patent number: 7504699
    Abstract: A method of forming an air gap or gaps within solid structures and specifically semiconductor structures to reduce capacitive coupling between electrical elements such as metal lines, wherein a norbornene-type polymer is used as a sacrificial material to occupy a closed interior volume in a semiconductor structure. The sacrificial material is caused to decompose into one or more gaseous decomposition products which are removed, preferably by diffusion, through an overcoat layer. The decomposition of the sacrificial material leaves an air gap or gaps at the closed interior volume previously occupied by the norbornene-type polymer. The air gaps may be disposed between electrical leads to minimize capacitive coupling therebetween.
