A novel two-dimensional mechanical metamaterial with negative Poisson’s ratio

, 2020
Artificial auxetic materials with negative Poisson’s ratio enable distinctive elastic response in the direction orthogonal to the loaded direction, i.e. shrinking when compressed and expanding when stretched, compared to conventional materials.

Crashworthiness of novel concentric auxetic reentrant honeycomb with negative Poisson's ratio biologically inspired by coconut palm

, 2020
Lightweight auxetic reentrant honeycombs (ARH) with negative Poisson's ratio (NPR) are very promising for crashworthiness applications due to high specific-strength and energy-absorption (EA).

Skin‐like Omnidirectional Stretchable Platform with Negative Poisson's Ratio for Wearable Strain–Pressure Simultaneous Sensor

Advanced Functional Materials, 2022
Conventional elastomeric polymers used as substrates for wearable platforms have large positive Poisson's ratios (≈0.5) that cause a deformation mismatch with human skin that is multidirectionally elongated under bending of joints.
