Abstract

A method for modulating roughness of a surface, comprising: providing a first pre-stressed electrically conductive layer (10) coupled to a dielectric elastic foundation (20) provided over a second conductive layer (30); and subjecting the two conductive layers to a voltage difference, thereby modulating the roughness of the first surface.
