For example, if you punch a bag full of water (like you would carry for hiking), the water within it will flow away from the point of impact. If the bag were full of an auxetic foam when you punched ...

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 ...

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 ...

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.

Los investigadores del Self-Assembly Lab del MIT han desarrollado recientemente un material adaptable que reacciona en respuesta a los cambios de temperatura. Conocido como Auxetics Heat-Active, el ...
