Path-guided wrinkling enables the fabrication of defect-free and arbitrary-shaped wrinkle patterns. R. Huang, Q. Liu, and co-workers describe on page 3010 an approach for the production of well-defined wrinkle structures using laser direct writing to make guiding paths in a metal/polymer bilayer, followed by thermal heating. They also introduce a new concept of the unit-wrinkle, through which more complex surface structures can be quantitatively designed and realized. This approach is suitable for making wavy-surfaced complexities and devices.
