Path‐guided wrinkling enables fabrication of defect‐free and arbitrary‐shaped wrinkle patterns. A new concept of unit‐wrinkle is introduced here, through which more complex wrinkle patterns can be quantitatively designed and realized by the processes of laser direct writing‐guided wrinkling. A simulation based on a composite film model agrees remarkably well with experimental data. Wavy‐surfaced devices are able to be produced by path‐guided wrinkling.
