The actuating device comprised a pristineMWNT yarn that was connected to the magnetic MWNT yarn, with a paddle attached between these yarns. The application of a magnetic field reversibly drove torsional actuation of up to 80° within ∼0.67 seconds. This magnetic actuator was remotely powered, and its actuation stroke was the same when the muscle array was at 20 °C and at -100 °C.enCC BY 3.0 (Attribution)©2018 The Royal Society of Chemistryhttp://creativecommons.org/licenses/by/3.0/Iron alloysMagnetismCarbon nanotubesMusclesNeodymiumWoolYarnarticleLee, D.
