Different from conventional materials, materials with negative Poisson's ratios expand
laterally when stretched longitudinally. Known as 'auxetic'materials, the effect means they …

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

The surge of interest in so-called “designer materials” during the last few years together with
recent advances in additive manufacturing (3D printing) techniques that enable fabrication …

Recently, auxetic honeycombs have attracted considerable attention for their excellent
mechanical properties, especially the potential applications for energy absorption. In this …

Over the last three decades but more particularly during the last 5 years, auxetic mechanical
metamaterials constructed from precisely architected polymer-based materials have …

A multi-step quasi-zero-stiffness metamaterial (MS-QZSM) is proposed, which exhibits
potential applications in various engineering scenarios, such as multi-vibration mitigation …

The mechanical responses of two novel kinds of two-dimensional (2D) mechanical
metamaterials containing opposite or parallel snapping curved (U-shaped) segments with …

Existing piezoresistive pressure sensors are limited because of the low sensitivity of
conventional piezoresistive porous materials, which have positive Poisson's ratio (PPR) …

To solve the problems that the existing negative Poisson's ratio (NPR) structures only exhibit
single plateau stage and irregular deformation modes, a novel hierarchical NPR structure …

It was supposed that auxetic structure with negative Poisson's ratio (NPR) expands under
stretch and could enhance the screw-bone fixation. In this study, the novel auxetic structure …
