Recent advances in lithography technology and the spread of 3D printers allow us a facile
fabrication of special materials with complicated microstructures. The materials are called …

Auxetic mechanical metamaterials (AMMs), as an exciting paradigm of metamaterials, have
attracted increasing attention due to their interesting mechanical properties (eg negative …

Missing rib auxetics with a reinforced central core may have tunable negative Poisson's
ratios (NPRs) and other mechanical parameters. In analogy with the other enhanced …

In analogy with the enhanced hexa-missing rib structure, a novel enhanced anti-tetra-
missing rib structure was proposed in this work. Using a simple energy-based approach …

Artificial auxetic materials with negative Poisson's ratio enable distinctive elastic response in
the direction orthogonal to the loaded direction, ie shrinking when compressed and …

Cellular auxetic materials possess a negative Poisson's ratio (NPR) and attractive
mechanical properties; however, these materials are limited by their low stiffness and …

The development of flexible strain sensors over the past decade has focused on accessing
high strain percentages and high sensitivity (ie, gauge factors). Strain sensors that employ …

Auxetic materials with negative Poisson's ratios have important applications across a broad
range of engineering areas, such as biomedical devices, aerospace engineering and …

This paper develops an auxetic (negative Poisson's ratio) piezoelectric energy harvester
(APEH) to increase the power output when harnessing strain energy. The APEH consists of …

Rock bolting technique is an important reinforcement measure in the geotechnical
engineering practice. New rock bolts have been continuously emerging through the …
