What is an auxetic material?
An auxetic material is a type of material that expands in all directions when stretched, rather than contracting like most materials. This unique property is due to its negative Poisson's ratio, which is a measure of how a material deforms when subjected to a strain. Auxetic materials have a wide range of potential applications, from biomedical devices to impact-resistant armor, due to their ability to absorb energy and distribute force more effectively than traditional materials.
