A New Way of Designing Auxetic Materials

Researchers at NIST and the University of Chicago have developed an advanced algorithm for designing auxetic materials, which expand when stretched and contract when compressed. This algorithm, which uses inverse design principles, allows precise control over the materials’ properties, optimizing them for various applications such as better cushioning in footwear, improved impact resistance in buildings, and more comfortable clothing. The innovation holds promise for making auxetics more common in everyday products.
