Abstract Intelligent stimuli‐responsive actuators that can convert environmental energies into mechanical works have garnered significant research interests. Among different actuation principles, Marangoni effect is distinguished due to simplicity, high efficiency, remote manipulation, and water environment adaptability. Nevertheless, both chemical physical face their own challenges with respect limited loading, precise light illumination, relatively poor motion controllability. In this study, floating based on graphene oxide foam (GOF), manipulable via dual effects magnetic field, are fabricated by Direct Laser Writing (DLW). This the first work realize dual‐Marangoni‐effect actuators. Specifically, it observed actuator driven attain an average speed of 0.57 rad s −1 . Meanwhile, photothermal capable reaching 0.17 , 1.34 cm under manipulation field. Multi‐field coupling make more flexible intelligent, promising potential for intelligent control biomedical engineering.

Abstract Meta-biomaterials are engineered biomaterials with unprecedented properties derived from their designed microscale structure, positioning them as promising candidates for developing medical devices (e.g., meta-implants). A significant challenge in meta-biomaterials lies effectively decoupling intrinsically intertwined mechanical elastic and shear moduli, Poisson’s ratio) morphometric porosity, connectivity, surface area). To address this challenge, we introduced non-stochastic unit cells featuring cubic isotropic three orthotropic planes of symmetry. We explicitly the geometrical relationships necessary to explore our design spaces, calculated pore sizes). employed a numerical homogenization method based on 3D voxelization approach model within space, representing empty solid phases binary format. Through an extensive number simulations (i.e., 43,000) multi-objective optimization technique, successfully isolated ratio while maintaining other effective anisotropy level), morphological relative mass density, size, tortuosity, surface/volume connectivity) transport parameters permeability) constant possible, average deviation below 9%.
