报告摘要：Biological systems exhibit intricate multiscale architectures that have been optimized over millennia, in which unit-cell geometries and material properties synergistically enhance mechanical and physical functionalities. Replicating such complexity in synthetic systems across nano- to macroscales remains a significant challenge, yet is crucial for achieving tailored collective behaviors. Here, we present an aluminum-based 3D lithography technique (AL-3DLitho) that integrates multiscale nanoimprinting and anodization to fabricate high-precision 3D anodic aluminum oxide templates with features spanning several orders of magnitude. By coupling AL-3DLitho with both low- and high-temperature deposition methods, we demonstrate the scalable fabrication of multiscale metamaterials featuring homogeneous and heterogeneous arrangements across at least 10⁷ length scales from atomic scale to centimeter scale. Furthermore, leveraging advanced data processing, our approach accelerates the discovery of novel metamaterials with desirable light-matter interactions and mechanical properties through precise structural tailoring across multiple scales. This framework paves the way for next-generation optoelectronic devices and flexible sensor technologies, bridging the gap between manufacturing techniques and advanced sensing applications.
