Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

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 …

Auxetic materials exhibiting a negative Poisson's ratio are of great research interest due to
their unusual mechanical responses and a wide range of potential deployment. However …

Material properties can be tailored through modification of their geometry or architecture.
With this concept, a lot of smart materials, metamaterials, and smart structures have been …

Abstract Electronic‐skin (E‐skin) has been investigated extensively for robotic tactile
sensing. However, E‐skin sensors based on flexible metamaterials are still challenging to …

Following high profile, life changing long term mental illnesses and fatalities in sports such
as skiing, cricket and American football—sports injuries feature regularly in national and …

Auxetic materials exhibiting a negative Poisson's ratio are shown to have better indentation
resistance, impact shielding capability, and enhanced toughness. Here, we report a class of …

Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual
negative Poisson's ratio well suited for designing shape transforming metamaterials. Current …

The emerging concept of mechanical meta-materials has received increasing attention
during the last few years partially due to the advances in additive manufacturing techniques …

Poisson's ratio had long been considered to be an intrinsic material property, confined within
a narrow domain and governed solely by the geometry of interatomic bonds. Materials with …
