An elastic membrane crumples under a lateral compressive force, forming irregular folds in the surface. In this work we reported a dielectric membrane that was crumpled by voltage in experiments. As the voltage ramps up, the boundary stress that used to tauten the membrane, reduces to zero, causing the membrane to experience loss of tension and then to crumple. A theoretical analysis is developed and discussed, resulting in an effective evaluation for the onset of crumpling instability and its harnessing.
