Beyond mechanochromism: Programmable multimodal actuation in cholesteric liquid crystal elastomer hollow fibers
Jiazhe Ma, John S. Biggins, Fan Feng +1
Cholesteric liquid crystal elastomers (CLCEs) change color under strain, offering attractive prospects for smart textiles, soft robotics, and photonic devices. However, the helical…
Programming evolution of geometry in shape-morphing sheets via spatiotemporal activation
Daniel Duffy, Itay Griniasty, John Biggins +1
Shape-programmed sheets morph from one surface into another upon activation by stimuli such as illumination, and have attracted much interest for their potential engineering applic…
Geometry, mechanics and actuation of intrinsically curved folds
Fan Feng, Klaudia Dradrach, Michał Zmyślony +2
We combine theory and experiments to explore the kinematics and actuation of intrinsically curved folds (ICFs) in otherwise developable shells. Unlike origami folds, ICFs are not b…
Curvature-driven instabilities in thin active shells
Andrea Giudici, John S. Biggins
Spontaneous material shape changes, such as swelling, growth or thermal expansion, can be used to trigger dramatic elastic instabilities in thin shells. These instabilities origina…
Shape programming lines of concentrated Gaussian curvature
D. Duffy, L. Cmok, J. S. Biggins +7
Liquid crystal elastomers (LCEs) can undergo large reversible contractions along their nematic director upon heating or illumination. A spatially patterned director within a flat L…
