Modeling of Shunted Piezoelectrics and Enhancement of Vibration Suppression through an Auxetic Interface

open access: yesMicromachines, 2023
In this study, a new technique is presented for enhancing the vibration suppression of shunted piezoelectrics by using an auxetic composite layer. Finite element models have been created to simulate the dynamic behavior of the piezoelectric composite ...

Bistable Networks Enable Complex Shape Changes

open access: yesAdvanced Science, EarlyView.
Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

MICROSTRUCTURE DESIGN AND MECHANICAL PROPERTIES ANALYSIS OF POROUS BONE WITH NEGATIVE POISSION’S RATIO (MT)

open access: yesJixie qiangdu, 2022
In view of the large difference between the elastic modulus of human bone structure and metal materials and the difficulty of control, the goal is to reduce or eliminate the “stress shielding” effect in a wide span, introduce a negative Poisson’s ratio ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Auxetic Textiles

open access: yesActa Chimica Slovenica, 2014
Common materials have Poisson’s ratio values ranging from 0.0 to 0.5. Auxetic materials exhibit negative Poisson’s ratio. They expand laterally when stretched longitudinally and contract laterally when compressed.

Exploring the potential: auxetic metamaterials as core elements in buckling restrained braces [PDF]

open access: yesArchives of Civil Engineering
Buckling restrained braces (BRBs) are now widely used in different seismic zones as lateral resisting systems due to their quasi-symmetric and stable cyclic behavior.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.
