Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Influence of porosity and architecture on the mechanical and acoustic properties of FFF‐printed PLA structures

Polymer International, EarlyView.
The influence of porosity and infill pattern (architecture) on the mechanical and acoustic properties of FFF‐printed PLA is investigated. Ultrasonic analysis highlights the dominant role of interlayer porosity, revealing anisotropic behavior and a transition in elastic properties with increasing porosity.

Investigating Three-Dimensional Auxetic Structural Responses to Impact Loading with the Generalized Interpolation Material Point Method

Buildings
Understanding three-dimensional (3D) auxetic structural responses to impact loading remains challenging due to large deformations involving failure evolution and the interaction between geometric and material instabilities. In this study, the Generalized

Fatigue response of auxetic structures: A review

The fatigue behavior of auxetic metamaterials is an interesting and recent research topic that will deserve future attention. How different geometries can interact with cyclic loadings is still an open question for these kinds of structures.

Development and Analysis of Different Density Auxetic Cellular Structures [PDF]

, 2015
Auxetic structures exhibit negative Poissons ratios in one or more directions. When stretched, they will become fatter or thinner when compressed, in contrast to conventional materials (like rubber, glass, metals, etc.) in the direction normal to the ...

Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

Small, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Auxetic oesophageal stents: structure and mechanical properties

Journal of Materials Science: Materials in Medicine, 2013
Oesophageal cancer is the ninth leading cause of malignant cancer death and its prognosis remains poor, ranking as the sixth most frequent cause of death in the world. This research work aims to adopt an Auxetic (rotating-squares) geometry device, that had previously been examined theoretically and analysed by Grima and Evans (J Mater Sci Lett 19(17 ...

Can Micro-Chiral Cellular Structures Be Auxetic?

, 2015
Auxetic materials with negative Poisson’s ratio have recently attracted the interest of the scientific community. This is because these materials have the potential to deliver specific functions thanks to a discretization of their constitutive matter
