Abstract
The surfaces of soft elastic films spontaneously form patterns. Application of an electric field above a critical value (fcric) to these patterns produces adhesive zones with distinct morphologies, such as pillars, large-amplitude fingers, or complete intimate contact (see Figure). These morphology changes, governed by film parameters such as stiffness and thickness, are explained by the physics of electrostatic-field-induced contact instabilities.
