This invention discloses a 3D-printed liquid crystal elastomer (LCE) actuator and its electrothermal actuation method, belonging to the field of smart materials technology. Addressing the problems of complex alignment processes, difficulty in balancing printability and actuation performance, and limitations in three-dimensional structures inherent in traditional LCE processes, this invention utilizes material-structure co-design to directly induce liquid crystal alignment using the shear force of the 3D printing nozzle and achieves local alignment programming.
