The new algorithm allows for fine-tuning this relationship to create auxetic materials that behave in ways you couldn't find in nature. "Our research is a beautiful example of theoretical, ...

Auxetic materials, which are engineered to expand when stretched, are not found in nature. Initially developed as foams with specialized microstructures, these materials can expand up to 30% before ...

Most materials get thinner when stretched. Take a rubber band, stretch it along its length, and it will shrink in the other two directions, getting narrower and thinner as you pull. But there are ...

Researchers at MIT’s Self-Assembly Lab have recently developed an adaptable material that reacts in response to changes in heat. Known as Heat-Active Auxetics, the material functions in a similar ...

Imagine pulling on the long ends of a rectangular piece of rubber. It should become narrower and thinner. But what if it instead became wider and fatter? Now, push in on those same ends. What if the ...

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 ...
