Abstract: Described is a method of forming a structure having viscoelastic properties. The method can include a) depositing a layer of droplets of a solidifying material and a non-solidifying material, the droplets being deposited according to an occupancy matrix specifying voxels for the solidifying and non-solidifying materials, the solidifying and non-solidifying material being interspersed within the occupancy matrix, the occupancy matrix being generated by a probabilistic function; b) exposing the droplets of solidifying material to ultraviolet radiation to cure the solidifying material; and c) repeating a) and b) to deposit additional layers of droplets of solidifying and non-solidifying materials, thereby forming the structure having viscoelastic properties.

Abstract: Non-planar shearing auxetic structures, devices, and methods are provided herein. In some embodiments, a non-planar shearing auxetic structure can include a mathematically compact surface with an auxetic pattern of repeating unit cells. The shearing auxetic structure can have a contracted configuration and an expanded configuration, and, when in the compact configuration, can be configured to move to the expanded configuration while generating a net shear on the surface. Shearing auxetic structures can have handedness and, in some embodiments, multiple handed shearing auxetic structures can be joined to create rigid or semi-rigid composite structures, e.g., by arranging differently-handed structures concentrically wherein two or more structures lock against each other. Handed shearing auxetic structures can also provide actuators to convert rotation or other motion to translation, volume expansion, bending, twisting, etc. These structures have many applications, e.g.
