Abstract
The material surfaces and interfaces are important because they are always in contact with the external environment. Wrinkle structures working on hydrogel surfaces and interfaces were studied. The results showed that the wrinkle structures strongly adhere to the hydrogels. Moreover, we succeeded in fabricating dynamic wrinkles with a wave–like structure, which provides important insights into the fabrication of wrinkle surfaces with controlled peristaltic flow direction like a conveyor belt.
