Abstract
Artificial Muscles In article number 2110360, Dong-Gyun Kim, Suk-kyun Ahn, and co-workers develop a new class of liquid crystal elastomers (LCEs) incorporating dynamic covalent bonds offering various useful properties such as welding, solution reprocessing, reprogrammable actuation, and self-healing that cannot be realized by conventional LCEs. By exploiting the dynamic features, an electrically powered artificial muscle and an artificial hand are fabricated, which can mimic various hand gestures by integrating a microcontroller through Joule heating.
