Abstract
An imaging system for a portable electronic device includes a variable aperture between a lens group and an image sensor. The variable aperture is defined by an electrochromic stack that defines a switching region and a central non-switching region. The electrochromic stack is defined by a layer of electrochromic material in which an electrochromic crystallite dispersion (e.g., nickel oxide) is suspended in a field of a lithiated ion conductor layer (e.g., lithiated tungsten nickel oxide).
