Artificial muscles transformed by fishing lines or sewing thread, have distinguished advantages, e. g., fast, scalable, nonhysteretic, and long-life, which have been proposed by Haines et al. [Science 343, 868 (2014)]. In this paper, we present a geometrical model to predict the effective Young’s modulus of the basic structure that is twisted by three fishing lines with the same diameter. Moreover, series of experiments are carried out to verify the present model, and it is found the theoretical calculations take good agreements with the experimental results.
