Mechanical metamaterials and beyond Article Open access 26 September 2023 Main Materials featuring tunable elastic properties1,2 offer tremendous possibilities for smart machines, robots, aircraft and other systems3,4,5. For example, robotic systems with variable stiffness can adapt to missions like grab...
Herein, the fundamental scientific theories behind this class of novel metamaterials, along with their fabrication techniques and potential engineering applications beyond mechanics are reviewed. Explored examples include the recent progresses for both mechanical and functional applications. Finally, the current...
Metamaterials are rationally structured composites, made of periodically or aperiodically organized building blocks, that manifest extreme properties and exotic functionalities that go beyond constitutive bulk materials1. Owing to the unprecedented possibilities enabled by metamaterials, the past decade has witne...
Low-density, high-strength, ductile metal mechanical metamaterials are in high demand for engineering applications but remain out of reach by the Gibson-Ashby model. Here, we demonstrate a new design concept based on a generalized theoretical model or an extended Gibson-Ashby model to overcome ...

Additive manufacturing and self-assembly techniques enable lattice design at the nanoscale; the scaling-up of nanolattice fabrication is currently the major challenge to their widespread use in technological applications. 展开 关键词: metamaterials nanoarchitectures nanolattices size effects ...
Rapid progress in additive manufacturing methods has created a new class of ultralight mechanical metamaterials with extreme functional properties. Their application is ultimately limited by their tolerance to damage and defects, but an understanding of this sensitivity has remained elusive. Using metamateria...
Suitably engineered mechanical metamaterials show static non-reciprocity—that is, the transmission of motion from one side to the other depends on the direction of that motion. When an object is pushed on one side and the opposite side moves by a certai
