Patents by Inventor Oibing Pei

Oibing Pei 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).

  • Electroactive polymer manufacturing
    Patent number: 8508109
    Abstract: Described herein are transducers and their fabrication. The transducers convert between mechanical and electrical energy. Some transducers of the present invention include a pre-strained polymer. The pre-strain improves the conversion between electrical and mechanical energy. The present invention provides methods for fabricating electromechanical devices including one or more electroactive polymers.
    Type: Grant
    Filed: March 8, 2011
    Date of Patent: August 13, 2013
    Assignee: SRI International
    Inventors: Ronald E. Pelrine, Roy D. Kornbluh, Oibing Pei, Seajin Oh, Jose P. Joseph

  • Electroactive polymers
    Publication number: 20060113880
    Abstract: The present invention relates to transducers, their use and fabrication. The transducers convert between mechanical and electrical energy. Some transducers of the present invention include a pre-strained polymer. The pre-strain improves the conversion between electrical and mechanical energy. The present invention also relates to devices including an electroactive polymer to convert between electrical and mechanical energy. The present invention further relates to compliant electrodes that conform to the shape of a polymer included in a transducer. The present invention provides methods for fabricating electromechanical devices including one or more electroactive polymers.
