Abstract
Magneto-responsive soft materials offer new opportunities in programmable surface engineering and microscale actuation. This study presents three strategies for controlling and fixing microscale architectures. Inspired by sharkskin, 3D microdenticle arrays are formed via magneto-mechanical actuation, enabling tunable anisotropic drag and friction through structural interlocking. A light-activated covalent adaptable network allows reversible, binder-free fixation using UV-induced disulfide exchange under ambient conditions. Magnetically actuated micropillar arrays exhibit multimodal, high-frequency oscillations, with motion controlled by magnetic alignment and geometry. These approaches enable dynamic reconfiguration of soft robotic and fluidic systems, offering spatiotemporal control of functional microactuators. The combined strategies form a versatile platform that connects biomimetic design with material programmability.
