Acoustic/elastic metamaterials exhibit a wealth of unusual properties conducive to wave
manipulation. This review outlines state-of-the-art developments from FPUT chains, granular …

Origami-inspired structures can manifest a range of interesting characteristics such as
reconfigurability and multi-stablity. Theoretically, the energy of rigid-foldable origami …

Mechanical bistable structures have two stable equilibria and can transit between them
under external stimuli. Due to their unique behaviors such as snap-through and substantial …

For the purpose of low-frequency vibration isolation and noise reduction, combined with the
nested mode of spider web, a new concave star bionic acoustic metamaterial was proposed …

So-called fragile topological states of matter challenge our conventional notion of topology
by lacking the robustness typically associated with topological protection, thereby displaying …

The confinement of waves within a waveguide can enable directional transmission of
signals, which has found wide applications in communication, imaging, and signal isolation …

Circuits provide ideal platforms of topological phases and matter, yet the study of topological
circuits in the strongly nonlinear regime, has been lacking. We propose and experimentally …

The parametric study of mechanical metamaterials enables the design of structures and
components with tailor-made properties. Novel topologies are designed through innovative …

Recent developments in topological mechanics have demonstrated the ability of Maxwell
lattices to effectively focus stress along domain walls between differently polarized domains …

Inspired by the kirigami and recombination mechanism, a kirigami flexible gripper is
presented. The configuration variation behaviors are realized by recombinant kirigami …
