Abstract
An electrostatic device has a fixed electrode and a flexible-sheet-variable electrode mounted adjacent thereto and insulated therefrom. Fixedly spaced from a portion of the variable electrode is a third electrode to provide a fixed capacity therebetween. A voltage applied between the fixed and third electrode activates the device, and direct ohmic contact to the delicate variable electrode is not necessary.
