In article number 1700828 , Dianyun Zhang, Luyi Sun, and co‐workers develop a series of moisture‐responsive wrinkled‐surface devices made using a poly(vinyl alcohol)–poly(dimethylsiloxane) bilayer system. These devices demonstrate reversible, temporary, or permanent wrinkles as moisturized, providing a route to tune the optical properties of a wrinkled surface for various applications, such as encryption devices, anticounterfeiting tabs, and water indicators.
