Programming mechanical metamaterials using origami tessellations

Origami structures, whose mechanical properties can be tuned by programing the crease network, have been sought in application including DNA origami nanorobots and deployable space structures. However, the existing researches mainly placed on the cylindrical origami tubes or the periodic cellular metamaterials, which are based on the stacking of individual 3D origami units. Here, we present a novel mechanical metamaterial, which can be...
