The use of wrinkling provides a generic route to stretchable metamaterials , with unprecedented terahertz tunability. The wrinkled metamaterial can be stretched reversibly up to 52.5%; the structural integrity can be maintained during at least 100 stretching/relaxing cycles. Importantly, the wrinkling of meta‐atoms offers a deterministic way to achieve controlled broadening of electrical resonance.
