Figure 1: Flytrap-inspired light-powered soft robot.
(a) A Venus flytrap at its open stage, (b) closes upon mechanical stimulation. Reprinted with permission from ref. 21. (c) Schematic drawing of the light-triggered artificial flytrap at its open stage, when no object has entered its field of view. No light is back-reflected to the LCE actuator, which remains in the open stage. (d) The flytrap closes when an object enters its field of view and causes optical feedback to the LCE actuator. Light-induced bending of the LCE leads to closure action, thus capturing the object. The insets of c and d show the schematic molecular orientation in LCE actuator at the open and closed stages.
