The high cost of powerful, large-stroke, high-stress artificial muscles has combined with performance limitations such as low cycle life, hysteresis, and low efficiency to restrict applications. [] Key Result Large-stroke tensile actuation was theoretically and experimentally shown to result from torsional actuation.

The feasibility of wearable, soft artificial muscles made by weaving and knitting, with tunable force and strain, is demonstrated by combining one of humankind’s oldest technologies, textile processing, with electroactive polymers.

Sheath-run artificial muscles

A muscle type is described 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, and Theory predicts the observed performance advantages of sheath-run muscles.
