Leaping liquid crystal elastomers
Science Advances, 2023 Snap-through mechanisms are pervasive in everyday life in biological systems, engineered devices, and consumer products. Snap-through transitions can be realized in responsive materials via stimuli-induced mechanical instability. Here, we demonstrate a rapid and powerful snap-through response in liquid crystalline elastomers (LCEs).

Biological liquid crystal elastomers [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002 Liquid crystal elastomers (LCEs) have recently been described as a new class of matter. Here we review the evidence for the novel conclusion that the fibrillar collagens and the dragline silks of orb web spiders belong to this remarkable class of materials. Unlike conventional rubbers, LCEs are ordered, rather than disordered, at rest.

Preparation of Monodomain Liquid Crystal Elastomers and Liquid Crystal Elastomer Nanocomposites [PDF]
Journal of Visualized Experiments, 2016 LCEs are shape-responsive materials with fully reversible shape change and potential applications in medicine, tissue engineering, artificial muscles, and as soft robots. Here, we demonstrate the preparation of shape-responsive liquid crystal elastomers (LCEs) and LCE nanocomposites along with characterization of their shape-responsiveness, mechanical ...

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions. [PDF]
Adv MaterAbstract Liquid crystal elastomers (LCEs) are promising building blocks for soft robots, given their large, programmable, reversible, and stimuli‐responsive shape change. Enhancing LCEs’ stiffness and toughness has been a longstanding desire previously explored by reinforcing them with fillers, crystalline microdomains, and ...

Liquid crystal elastomers wrinkling [PDF]
Nonlinearity, 2021 Abstract When a liquid crystal elastomer layer is bonded to an elastic layer, it creates a bilayer with interesting properties that can be activated by applying traction at the boundaries or by optothermal stimulation. Here, we examine wrinkling responses in three-dimensional nonlinear systems containing a monodomain liquid crystal ...
