Heterogeneous membrane with rigid elements has been extensively applied in flexible electronic systems and in aerospace structures. Here, we study the surface wrinkling of such heterogeneous membrane. Experiment, theoretical analysis and numerical simulation are performed to quantify the effect of rigid elements on the wrinkle pattern of the membrane. The characteristics of wrinkles related to the positions of rigid elements and stretching strain are investigated and the underlying mechanism is revealed. It is found that wrinkle patterns can be tailored by varying the positions of the rigid elements to achieve desired functions. Our results can provide insightful ideas to understand the wrinkling phenomenon of heterogeneous membranes and create novel wrinkle patterns in a controllable way.
