  • Optical lens displacement systems
    Publication number: 20100033835
    Abstract: The present invention provides optical systems, devices and methods which utilize one or more electroactive polymer actuators to adjust an optical parameter of the optical device or system.
    Type: Application
    Filed: December 10, 2007
    Publication date: February 11, 2010
    Applicant: Artificial Muscle, Inc.
    Inventors: Jonathan R. Heim, Ilya Polyakov, Alireza Zarrabi, Otto Hui
  • FLUID CONTROL SYSTEMS EMPLOYING COMPLIANT ELECTROACTIVE MATERIALS
    Publication number: 20090250021
    Abstract: The present invention includes fluid control systems employing compliant electroactive materials.
    Type: Application
    Filed: October 2, 2008
    Publication date: October 8, 2009
    Applicant: Artificial Muscle, Inc.
    Inventors: Alireza ZARRABI, Ilya POLYAKOV, Jonathan R. HEIM
  • ELECTROACTIVE POLYMER TRANSDUCERS BIASED FOR INCREASED OUTPUT
    Publication number: 20090152995
    Abstract: Electroactive polymer transducers are disclosed. They are biased in a manner that provides for increased force and/or stroke output, thereby offering improved work potential and power output capacity. The biasing may offer additional or alternate functional advantage in terms of matching transducer performance with a given application such as a normally-closed valve. The improved biasing (including increased output biasing) may utilize negative spring rate biasing and/or a combination of negative or zero-rate biasing with positive rate biasing to achieve the desired ends.
    Type: Application
