Auxetics defy common sense, widening when stretched and narrowing when compressed. NIST researchers have now made the process of using them much easier. Such common-sense-defying materials do exist.

The study of auxetic materials and mechanical metamaterials has ushered in a new era in materials science, where structural design and geometry enable properties beyond those of conventional materials ...

Why auxetic materials offer some unique advantages in sensor fabrication. How additive manufacturing was used with autextic materials to create unique pressure and force sensors. The structure and ...

The Atlantic wolffish is known for its powerful bite, capable of crushing hard-shelled prey with ease. Now, researchers have discovered that the fish's teeth don't just withstand these extreme forces, ...

Osteodentin found in the core of this bottom-dwelling Atlantic Ocean predator's teeth could inspire new designs for stronger, ...

Auxetic metamaterials can improve comfort, fit, and impact protection in products such as body protection and helmets. They exhibit synclastic curvature, meaning they form a “dome shape” when bent, ...

If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Auxetics defy common sense, widening when stretched and narrowing when compressed. Researchers have now made the process of using them much easier, paving the way for new types of auxetic products -- ...

Such common-sense-defying materials do exist. They’re called auxetics, and they have a raft of unique properties that make them well-suited for sneaker insoles, bomb-resilient buildings, car bumpers ...
