A patterned adhesive, based on surface wrinkling through swelling of a laterally confined polymer film, is presented by Alfred J. Crosby and co‐workers on p. 711. The image highlights the interface between the wrinkles (bright cylinders) of the patterned adhesive separating from a glass substrate (circular region). Enhanced control of adhesion is attributed to contact line splitting, which is fundamental to adhesion control in numerous examples in nature, for example, the gecko.
