Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...
