Negative Poisson's ratio (NPR) materials —which shrink along one axis when compressed along an orthogonal one—are currently composed of reentrant cells with dimensions greater than 1 mm. The fabrication of NPR materials from various materials and in various cell geometries with dimensions in the micrometer range, for example the epoxy NPR material shown in the Figure, is described.
