An electrostatically actuated fluidic device capable of providing a
variable focal length lens is disclosed. The device includes an elastic
capacitor section, an elastic lens section in fluid communication with
the capacitor section, the elastic lens section being characterized by a
focal length and a fluid capable of fluid motion disposed at least
partially in the capacitor and lens sections. A voltage may be applied to
the capacitor section causing it to deform, which causes a portion of the
fluid to flow into or out of the lens section. As a result, a change in
volume of fluid in the lens section causes it to deform resulting in a
variation in the focal length of the lens section.
