Torsional actuation of a two-ply, sheath-core muscle that was electrically driven at 1.8 Hz. When charged, the paddle in the middle rotates as a result of tensile actuation being converted to torsional rotation within the twisted, plied muscle. This material relates to a paper that appeared in the July 24, 2015, issue of Science, published by AAAS. The paper, by Z. Liu at University of Texas at Dallas in Richardson, Texas, and colleagues was titled, "Hierarchically buckled sheath-core fibers for superelastic electronics, sensors, and muscles."
