Liquid crystal elastomers (LCEs) are active soft

matter-based materials with strong stimulus responsiveness

and reversible, large-shape morphing capabilities. LCEs have

demonstrated

broad

and

growing

applications

in

soft

robotics, wearable devices, artificial muscles, and optical

machines. The actuation intelligence and advanced function-

ality of LCEs depend on the smartness and properties of

structures. In this review, we discuss recent advances in

structure-induced intelligence of LCEs, specifically the integra-

tion of structural properties with the alignment and process-

ing of LCEs. The structural design principles for three

categories consisting of common structures (film, fiber, and

tubule), smart structures (origami, kirigami, mechanical meta-

material, topology, and topography), and complex structures

(monolithic and integrated) are presented. Various alignment

controls of LCEs, including mechanical, surface, field-assisted,

and shear alignment, are capable of inducing structural

properties. The coupling and collaboration mechanisms of

the LCE structures and the generated functions are discussed.

The review concludes with perspectives on current challenges

and emerging opportunities.
