Onset of criticality in hyper-auxetic polymer networks
Nature Communications, 2022 Auxetic materials are characterized by a negative Poisson’s ratio - they become thicker when stretched. Here, authors reach the limit of auxetic behavior, known as hyper-auxetic, in polymer networks, hitting an unconventional mechanical critical point.

Theory of Strains in Auxetic Materials [PDF]
Journal of Superconductivity and Novel Magnetism, 2012 Auxetic materials, or negative-Poisson's-ratio materials, are important technologically and fascinating theoretically. When loaded by external stresses, their internal strains are governed by correlated motion of internal structural degrees of freedom.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials. [PDF]
Adv Sci (Weinh)This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

Nano‐ and Micro‐Auxetic Plasmonic Materials [PDF]
Advanced Materials, 2016 Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical ...

A three step recipe for designing auxetic materials on demand
Communications Physics, 2022 Unlike regular elastic materials, when auxetic materials are compressed, they become thinner in the direction perpendicular to the applied force. Despite their outstanding mechanical properties, a systematic design of new and controlled auxetics remains ...

Hierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites [PDF]
, 2013 In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb.
