The pulse DC sputtered iridium oxide coating is achieved through a mixture ratio of oxygen and argon gases, a sputtering power of between 75 to 125 W, a chamber pressure ranging from about 20-30 mTorr, and a frequency ranging from 50 kHz to 150 kHz. The coated electrode may be used to facilitate the injection of electrical charge stimulation and/or monitor biorhythms of cardiac and neurological tissue.

  • Patent number: 8845931
    Abstract: A method for preparing a nanometal-polymer composite conductive film includes the steps of (1) mixing a metal oxide with a polymer solution; (2) coating a substrate with a solution resulting from step (1), followed by drying the resultant solution to form a film; (3) performing thermal treatment on the film formed in step (2); and (4) sintering the film thermally treated in step (3). The method dispenses with any reducing agent or dispersing agent but allows nanometallic particles to be formed in situ and thereby reduces surface resistance of the polymer film efficiently.

  • Publication number: 20140262499
    Abstract: In some embodiments, a system includes a first portion, a second portion, and a third portion of an electrical conductor. Each portion is electrically coupled to the other two portions. The first, second, and third portions are configured such that substantially no current induced in and/or supplied to the first portion is conducted to the third portion of the electrical conductor. The third portion of the electrical conductor is also thermally coupled to the first and second portions of the electrical conductor. The third portion of the electrical conductor is configured to transfer thermal energy from the first portion of the electrical conductor to an edge portion of the laminated composite assembly.
