1. A microblind system comprising:

  • an array of microblinds, each comprising a stressed conductive layer having an anchor portion attached a substrate in the form of a window, illuminated panel, or supporting layer to be applied to a window or illuminating panel, and an overhanging mobile portion;

    said stressed conductive layer being naturally in a curled configuration and being responsive to electrostatic forces to mutate between a deployed configuration wherein said overhanging mobile portion obscures the substrate and said curled configuration wherein said overhanging mobile portion exposes the substrate; and

    a transparent conductive layer for applying an electric field to said microblinds, andwherein said anchor portions are in the form of a region comprising said stressed layers interdiffused with a remnant of a sacrificial layer.
