Summary: This study reports an optically powered soft material strip that can perform nonreciprocal, cilia-like, self-sustained oscillation under water. The actuator is made of planar-aligned liquid crystal elastomer responding to visible light. Two laser beams from orthogonal directions allow for piecewise control over the strip deformation, enabling two self-shadowing effects coupled in one single material to yield nonreciprocal strokes. The results demonstrate autonomous microfluidic pumping, translocation of a micro-object, and coupling between two oscillating strips through liquid medium interaction, offering new concepts for non-equilibrium soft actuators that can perform bio-like functions under water.

Summary: The widespread use of magnetic soft robots is hindered by complex control paradigms and challenges in fabricating devices across different scales. In this study, advancements in fiber-based actuators and magnetic elastomer composites are utilized to create 3D magnetic soft robots controlled by one-directional fields. These robots can crawl or walk in magnetic fields orthogonal to their motion plane. They can also act as cargo carriers and be simultaneously controlled in opposite directions using a single stationary electromagnet. This scalable fabrication and control approach opens up possibilities for future applications of magnetic soft robots in environments with constrained and complex fields.

These GQDs were doped with elements B, N, O, S, and P at dopant percentages of 1.5%, 3%, 5%, and 7%. The results show the systematic variations in the UV-vis absorption spectra of the GQDs with changes in size, dopant type, and dopant percentage.
