Abstract

The design of the electrochromic component of an instrumented contact lens capable of dynamically modifying its color is presented. The device is based on two electrochromic pi-conjugated polymers (CPs) deposited on two electrodes separated by an electrolyte medium. Yellow and cyan electrochromic CPs with two color states are combined to provide a tuneable tint of the eye iris, from green to cyan. The device can switch from green, in which both electrodes are colored, to cyan, in which only the cyan electrode is colored. The additive microsystem process with successive assembling steps allowing the realization of the bichromatic cell in the scleral contact lens is presented, as well as the characterization of the colorimetry and switching dynamics.
