  Mechanical metamaterials with complex microstructures have superior physical
properties such as graded stiffness, negative Poisson's ratio, and advantage in
energy absorption. In recent years, origami provide many inspirations in the
geometry structure of the metamaterials. Here we present a modular origami
inspired reconfigurable metamaterial. Our approach exploits a transformable
module consisted of the Sarrus linkage and planar four-bar linkage, and the
modules are connected following a tessellation pattern to form a periodic
structure. Different arrangements, module shapes and grid pattern of the
metamaterial are discussed, and the loading capacity and stiffness variation
are analysed experimentally. The proposed material can be used to realize
reconfigurable structures or architectures over a wide range of length scales.
