Stimuli-responsive

patterned photonic actuators, characterized by their patterned

nano/microscale structures and capacity to demonstrate synergistic color

changes and shape morphing in response to external stimuli, have attracted

intense scientific attention. However, traditional patterned photonic actuator systems still face limitations such as

cumbersome and time-consuming preparation processes and small-scale

deformations. Herein, we introduce a facile approach involving an athermal

embossing technique to rapidly fabricate patterned photonic actuators based on near-infrared (NIR) light-responsive liquid crystal

elastomers. The resulting patterned photonic actuators demonstrate remarkable features, including brilliant

angle-dependent structural color, complex three-dimensional actuation, and good

color durability under NIR light stimulation. As illustrative demonstrations of

the proof-of-concept, we fabricate two light-fuelled patterned photonic soft actuators: a butterfly-inspired actuator that

can produce wing-flapping dynamic changes in structural color, and an origami

crane-shaped actuator with shape memory, structural color information storage,

and dynamic display properties. This strategy provides distinct insights into

the design and fabrication of various patterned photonic soft robotic devices and intelligent actuators.
