ELECTROACTIVE POLYMER ACTUATED APERTURE

摘要

An apparatus is disclosed. The apparatus includes a rigid frame, an electroactive polymer film defining an aperture where the electroactive polymer film has a first and second side, A first electrode is located on the first side of the electroactive polymer film and a second electrode is located on the second side of the electrotactive polymer film. The aperture is configured to deform upon the application M a« electric, voltage potential to the first and second electrodes. A. method of making an electroactive device is also disclosed. The method includes positioning an electroactive polymer film within a rigid frame and forming an aperture within the electroactive polymer film. Another apparatus is disclosed. The apparatus includes a rigid frame, a first diaphragm, a second diaphragm attached to the first diaphragm, and an aperture defined at a center portion of the first and second diaphragms.
