The continuous advancement of multifunctional materials is reshaping our way of life and
paving the door for innovative things for us to probe the world and ourselves. Multifunctional …

Mechanical metamaterials have been attracting increasing attention for a wide range of
industrial applications, such as energy storage, biomedical, sensors, robotics, etc., owing to …

The paper proposes a novel polygonal negative stiffness (NS) metamaterial composed of
folded beams and stiffening walls, which exhibits excellent performance in attenuating …

Structural metamaterials presenting negative values of one or more mechanical and
thermomechanical indices–namely the Poisson's ratio, the linear compressibility, and the …

Auxetics display the anomalous property of expanding laterally when uniaxially stretched,
that is, a negative Poisson's ratio, a property that arises from 1) the presence of specific …

A partially-auxetic metamaterial is introduced, inspired by the Maltese cross. Each unit of this
metamaterial consists of a pair of counter-rotating equal-armed crosses, which is …

Curved displays can adjust their shape to accommodate different objects and are used in
electronics and decorative lighting. Due to the immutable pixel spacing, existing commercial …

Auxetic structures exhibit unusual changes in size, expanding laterally upon stretching
instead of contracting. This paper presents this effect in a failsafe mode in structures made of …

The re-entrant honeycomb microstructure is one of the most famous, typical examples of an
auxetic structure. The re-entrant geometries also include other members as, among others …

In this work, through the use of a theoretical model, we analyse the potential of a specific
three-dimensional mechanical metamaterial composed of arrowhead-like structural units to …
