Patents by Inventor Geoff Spinks

Geoff Spinks has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Control of shape of an implantable electrode array
    Patent number: 8843216
    Abstract: An implantable electrode array includes an elongated carrier (20) and a plurality of electrodes mounted within the carrier. A actuator adjusts the curvature of the carrier and can be controlled by varying an electric potential applied to the actuator. The actuator is based on an electrochemical cells and may be a conducting polymer based actuator.
    Type: Grant
    Filed: December 10, 2002
    Date of Patent: September 23, 2014
    Assignee: Cochlear Limited
    Inventors: Gordon Wallace, Geoff Spinks, Dezhi Zhou, Claudiu Treaba, Peter Gibson, Elaine Saunders, Jin Xu, Robert Cowan
  • Ionic solvents used in ionic polymer transducers, sensors and actuators
    Patent number: 8172998
    Abstract: Ionic liquids are incorporated into transducers, actuators or sensors which employ the ionic polymer membranes. The ionic liquids have superior electrochemical stability, low viscosity and low vapor pressure. The transducers, actuators and sensors which utilize ionic polymer membranes solvated with ionic liquids have long term air stability. Superior results are achieved when a conductive powder and ionomer mixture is applied to the ionic polymer membrane to form the electrodes during or after the ionic liquid is imbibed into the ionic polymer membrane.
