Wang, Yunpeng published the artcileBioinspired Construction of Artifcial Cardiac Muscles Based on Liquid Crystal Elastomer Fibers, Name: Pentaerythritol tetra(3-mercaptopropionate), the main research area is artificial cardiac muscle liquid crystal elastomer fiber arterial blood.
Human muscles, including skeletal, smooth, and cardiac muscles, are able to perform diverse deformations and execute complex biofunctions stimulated by nerve signals. Similarly, liquid crystal elastomer (LCE), which can respond to external stimuli with large and reversible deformations, demonstrates superior advantages to mimic nature muscles to fabricate artifcial muscles. Till now, LCE has been utilized to simulate deformations and related functions of skeletal and smooth muscles. However, limited by the existing fabrication strategy, employing LCE to mimic the motion of cardiac muscles and further realizing the structure-determined pumping functions, is still an open challenge. Learning from the specifc spatial arrangements and synergistic actuation of cardiac muscle fibers within human heart, a simple and general strategy to construct artifcial cardiac muscles with LCE fbers is proposed. In this work, LCE fbers with similar modulus and actuation behavior to muscle fibers are fabricated and spatially arranged in biol. architectures as cardiac muscle fibers. As a result, artifcial cardiac muscles are constructed and are able to perform simultaneous contraction and torsion motions, realizing heart-pumping functions. This general strategy should be also applicable for other smart materials to conduct challenging tasks.
