Abstract


  • Although guest-filled carbon nanotube yarns provide record performance as torsional and

    tensile artificialmuscles, they are expensive, and only part of themuscle effectively contributes

    to actuation.We describe a muscle type that provides higher performance, in which the

    guest that drives actuation is a sheath on a twisted or coiled core that can be an inexpensive

    yarn. This change from guest-filled to sheath-run artificial muscles increases the maximum

    work capacity by factors of 1.70 to 2.15 for tensile muscles driven electrothermally or by

    vapor absorption. A sheath-run electrochemical muscle generates 1.98 watts per gram of

    average contractile power—40 times that for human muscle and 9.0 times that of the

    highest power alternative electrochemical muscle.Theory predicts the observed performance

    advantages of sheath-run muscles.
