ABSTRACT:
An exemplary aperture apparatus includes a transparent substrate, a number of EAP sheets supported by the substrate and spaced apart from each other, a first electrode, a second electrode and an aperture sheet. Each of the EAP members includes a fixed first end and an opposite second end movable relative to the substrate. The first electrode and the second electrode contact the first surface at the first end of each of the EAP members. The aperture sheet is made of black rubber and is positioned on the second surface of the EAP members. The second ends of the EAP members are fixed to inner wall of the aperture sheet. The EAP members are deformable in response to a voltage applied between the first and second electrodes so as to vary the size of the aperture.
