Origami is the art of folding two-dimensional (2D) materials, such as a flat sheet paper, into complex and elaborate three-dimensional (3D) objects. This study reports origami-based metamaterials whose electromagnetic responses are dynamically controllable via switching state Miura-ori split-ring resonators. The deformation unit along third dimension induces net electric magnetic dipoles resonators parallel or anti-parallel to each other, leading strong chiral responses. Circular dichroism high 0.6 experimentally observed while chirality realized by controlling direction kinematics. In addition, relative density origami can be dramatically reduced only 2% that unfolded structure. These results open new avenue toward lightweight, reconfigurable, deployable metadevices with simultaneously customized mechanical properties.
