Honeycombs are ultra-light materials with outstanding mechanical properties, which mainly
originate from their unit cell configurations rather than the properties of matrix materials …

Abstract 4D (bio‐) printing endows 3D printed (bio‐) materials with multiple functionalities
and dynamic properties. 4D printed materials have been recently used in biomedical …

This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

Auxetic structures have theoretically superior bending resistance that was previously
inaccessible. Compared with the planar two-dimensional (2D) auxetic structures, the three …

Practical applications of mechanical metamaterials often involve solving inverse problems
aimed at finding microarchitectures that give rise to certain properties. The limited resolution …

Metamaterials are engineered materials with unusual, unique properties and advanced
functionalities that are a direct consequence of their microarchitecture. While initial …

Double arrowed honeycomb (DAH) is a typical auxetic material with negative Poisson's ratio
(NPR) and excellent mechanical properties, showing a wide application prospect in …

Traditional 3D auxetic materials face significant limitations, marked by low stiffness and
pronounced anisotropy. To address these challenges, here a new kind of 3D origami …

Auxetic honeycombs usually feature a single plateau stress, which hinders their
multifunctional applications. In this work, we aim at investigating the two plateau …
