摘　　要：随着自然界的不断进化,许多生物都表现出了适应环境的独特行为,为研究人员开发适应环境的智能材料和仿生软执行器提供了灵感。液晶弹性体(Liquid Crystal Elastomers,LCEs)软执行器作为智能软机器人的代表性执行元件,具有液晶各向异性和橡胶软弹性,在外部环境刺激下能够实现可逆、复杂的形状变化和运动能力。基于光驱动的LCEs执行器具备多种优势,包括强大的远程控制能力、迅速的响应时间以及高效的能量积累和释放机制。本文介绍了光控仿生LCEs软执行器中的LCEs形状变化响应机制及其性能,并展望了基于仿生设计的光控LCEs软执行器在智能机器人领域的应用前景。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.
