Abstract
An electrochromic device comprises, in a layered structure, a first electrode, an electrochromic material, an electrolyte and a back electrode which is of a material different than said first electrode. The device is characterized as having a nonlinear voltage response, a well defined threshhold, and an internal electromotive force which is uniquely determined by the color state of the device.
