제목 Snap-through induced locomotion of liquid crystal elastomer filaments
초록 Here, the LCE actuator in fibrous form, a pre-curved single LCE fiber is used as a building block to produce self-regulated actuation from N-fold closed loops where each fiber is geometrically constrained by the others. Upon heating, each fiber in the ring undergoes a twist-driven buckling, followed by snap-through. Since the rings are connected, the boundary conditions and number of fibers per ring play important roles in the actuation response. Through these results, I’d like to highlight the combination of geometric designs and anisotropic polymeric network of LCE materials is able to offer new insights to develop self-regulated complex motion of soft actuators.
