ABSTRACT:
A method and apparatus for detecting random electrostatic discharge events is disclosed in which the electrostatic discharge indicator is "Electric Paper". The "Electric Paper" has a plurality of spheres having one hemisphere of one color and the other hemisphere of another color. The spheres rotate when an electric field is applied to them and are sensitive enough to respond to electrostatic discharge events. The "Electric Paper" may be pre-imaged so that a pattern indicating the state of the paper is visually ascertainable.
