Solvent‐responsive surfaces are fabricated by osmotically‐driven wrinkling with hierarchical morphology and controlled wavelength. By taking advantage of reversible wrinkling mechanisms and controlling the region with moduli‐mismatch, we demonstrate several applications such as reversible channels, tunable microlens arrays, and guided colloidal pattern formation.
