As nature continues to evolve,many organisms exhibit unique behaviors that are adapted to their environments,providing inspiration for researchers to develop environmentally adapted smart materials and bionic soft actuators.Liquid crystal elastomers(LCEs)soft actuators,as representative actuators for intelligent soft robots,have liquid crystal anisotropy and rubbery soft elasticity,which enable reversible and complex shape changes and locomotor capabilities in response to external environmental stimuli.Light-driven LCEs-based actuators offer a variety of advantages,including powerful remote control capability,fast response time,and efficient energy accumulation and release mechanisms.In this paper,we introduce the LCEs shape change response mechanism and its performance in the light-driven bionic LCEs soft actuators,and look forward to the application prospect of the light-driven LCEs soft actuators based on bionic design in the field of intelligent robotics.
