Multifunctional and Reprogrammable Magnetoactive Graphene Oxide Origami.

ABSTRACT: Magnetoactive materials, which change shape in response to magnetic fields, hold significant potential for applications in soft robotics, biomedical devices, and morphable structures. However, existing systems often suffer from complex fabrication processes, limited geometric customizability, and inefficient magnetization reprogramming strategies, especially for 3D structures. Here, lightweight magnetic graphene oxide (MGO) bilayer films incorporating hard-magnetic microparticles are introduced to enable fast, precise, and stable shape-morphing under magnetic actuation, including in aqueous environments. The paper-like nature of MGO films allows low-cost and straightforward fabrication of customized structures through post-processing steps such as cutting, folding, and assembly. In additio
