2 March 2012Electro-active multi-layer fluidic lens of PDMS membrane for optical zooming system
A full fluidic lens system consisting of multi-layers of PDMS membranes, which each builds single convex/concave
lens, whose lens aperture is ~4mm, was fabricated. It was operated with magnetic attraction/repulsion induced by voicecoil
coiled in between magnets adhesively bonded to each PDMS membrane. It has shown a smooth and fast
controllability of the focal-length control versus the applied voltage and quite good image of the target at the distance
from 10 mm to 5 m. To verify zooming function of lens, images captured by digital camera was attached, and it also
shows good image magnification.
