Mechanical performance of auxetic polyurethane foam for antivibration glove applications [PDF]
, 2005 In this study the static and dynamic characteristics of conventional open cell polyurethane (PU), of auxetic (negative Poisson’s ratio) and of iso-density foams were analysed.

Tensioned Auxetic Structures Manual Calculus
Journal of Architectural Environment & Structural Engineering Research, 2019 Auxetic materials have several properties very useful to be applied to architecture structures. This paper is aimed to test structurally a specific auxetic structure model. This hypothesis will be check: if auxetic materials have innovative properties in nanoscale then they will also have these properties in macroscale.

Advanced Materials Technologies, EarlyView.This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics
Advanced Materials Technologies, EarlyView.A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Random auxetics from buckling fibre networks
Nature Communications, 2019 Auxetic materials have usually been developed with periodically arrange structures. Here, the authors electrospin fibre networks, and show both theoretically and experimentally that these random structures have pronounced auxetic behaviour with negative ...

Active Auxetic Heel Support for Achilles Tendon Therapy [PDF]
, 2018 The Achilles tendon, which stretches from the calf to the ankle, can be injured due to repeated daily activities or overstretching. In severe cases a tear in the tendon can prevent athletes from performing in games as well as individuals from completing ...

A class of auxetic three-dimensional lattices
, 2015 We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed in order to have omni-directional Poisson's ratio arbitrarily close to the stability limit -1.
