Inspired by kirigami, a type of Japanese paper art, researchers have created a new material that transforms from a grid into ...

When a user pulls the string, the structure moves smoothly into its final 3D form. If the user releases the string, the ...

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 -- ...

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in ...

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 ...

Most of us think we have a pretty solid grasp on basic physics, and one of the assumptions we've come to form is that any material gets thinner as it's stretched. It makes sense, since the same amount ...

Regardless of whether it is strained or compressed, the new material always expands. Copyright: Thomas Heine et al. Researchers have discovered a two-dimensional ...

Like most materials, an elastic band gets thinner when it is stretched. But some materials behave in the opposite way—they grow thicker when stretched and thinner when compressed. These ...

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.

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 ...
