Miura-ori and Yoshimura crease patterns — rigid origami tessellations used in deployable structures, solar panels, and metamaterials. Mountain folds (red) and valley folds (blue) alternate to enable one-DOF folding.

Miura-ori: one degree of freedom — unfolds flat from a single pull. Used in solar panel deployment (IKAROS satellite 2010).
