  • Coiled and non-coiled twisted nanofiber yarn torsional and tensile actuators
    Patent number: 9784249
    Abstract: Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate torsional and/or tensile actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described.
    Type: Grant
    Filed: January 30, 2015
    Date of Patent: October 10, 2017
    Assignee: The Board of Regents, The University of Texas System
    Inventors: Na Li, Carter S. Haines, Marcio D. Lima, Monica Jung De Andrade, Shaoli Fang, Jiyoung Oh, Mikhail E. Kozlov, Dongseok Suh, Ray H. Baughman
