Abstract
An auxetic fiber and corresponding material that not only responds to an external force, but also responds to moisture. The auxetic fiber is made in part from a moisture activated shrinking filament. Even if no external force is applied to the fiber, a pseudo tensile force is created by wetting the auxetic fiber.
