Recently, wrinkling has extensively investigated as a new type of substrate for mechanical, optical and electrical properties. The geometry of the wrinkles are determined by a compressive strain between a stiff top layer on a soft material. Herein we control the geometry of the wrinkles through manipulation of the time of UVO exposure and prestrain ratio. Also, we applied the wrinkle structure as a sensitive tactile sensor application due to the wrinkles has structural sensitivity compared conventional flat surface. |
