Abstract

A membrane device is provided in which a plurality of ridges (14) and recesses (16) are formed proximate to a substrate (12). Electrodes (18) are formed within the recesses (16). A spacer (20) supports a membrane (22). Application of a potential difference between the membrane (22) and the electrodes (18) allows for deflection of the membrane (22) toward the electrodes (18).
