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.
