We actuate designed liquid crystal elastomer sheets to form curved folds that bear non-zero Gaussian curvature and have unusual mechanics.
Abstract Crawling by means of the traveling deformation a soft body is widespread mode locomotion in nature—animals across scales, from microscopic nematodes to earthworms gastropods, use it move around challenging terrestrial environments. Snails, particular, mucus—a slippery, aqueous secretion—to enhance interaction between their ventral foot and contact surface. In this study, millimeter‐scale crawling robot demonstrated that uses similar mechanism efficiently variety configurations: on...
Despite spectacular progress in microfluidics, small-scale liquid manipulation, with few exceptions, is still driven by external pumps and controlled large-scale valves, increasing cost size limiting complexity. By contrast, optofluidics uses light to power, control monitor potentially allowing for small, self-contained microfluidic devices. Here we demonstrate a soft light-propelled actuator made of crystal gel that microlitre volumes water. The strip actuating material serves as both pump...
Abstract In the report we demonstrate how, using laser light, effectively trap gas bubbles and transport them through a liquid phase to desired destination by shifting beam position. The physics underlying effect is complex but quite general as it comes from limited two-dimension, well-known, Marangoni effect. experimental microscope-based system consists of thin layer placed between two glass plates containing dye dissolved in solvent light that strongly absorbed dye. This point-like heat...
Abstract The ability to grip and handle small objects, from sub‐millimeter electronic components single‐micrometer living cells, is vital for numerous ever‐shrinking technologies. Mechanical grippers, powered by electric, pneumatic, hydraulic or piezoelectric servos, are well suited the job at larger scales, but their complexity need force transmission prevent miniaturization remote control in tight spaces. Using liquid crystal elastomer microstructures that can change shape quickly...
The photomechanical response of liquid crystal polymer networks (LCNs) can be used to directly convert light energy into different forms mechanical energy. In this study, we demonstrate how a traveling deformation, induced in ring by spatially modulated laser beam, drive the (the rotor) rotate around stationary element stator), thus forming light-powered micromotor. film is modeled numerically, LCN molecular configurations are studied, and performance 5.5 mm diameter motor characterized.

In this paper, we present electrooptical properties of hybrid liquid crystalline systems, which contained CdSe quantum dots (QDs). We have shown by experiments degenerated two-wave mixing and transverse conductivity measurements that crystal cells filled with nematic doped semiconductor nanoparticles exhibit photorefractive effect associated photoconductivity appearing in the system. also mathematical model, explains relationship between layer on QDs reside generation holographic gratings....
We combine theory and experiments to explore the kinematics actuation of intrinsically curved folds (ICFs) in otherwise developable shells. Unlike origami folds, ICFs are not bending isometries flat sheets, but arise via non-isometric processes (growth/moulding) or by joining sheets along boundaries. Experimentally, we implement both, first making joined from paper, then fabricating liquid crystal elastomer (LCE) that morph into upon heating/swelling programmed metric changes. Theoretically,...
