Meniscus‐Guided Micro‐Printing of Prussian Blue for Smart Electrochromic Display (Adv. Sci. 3/2023)

Abstract

Meniscus‐Guided Printing

Meniscus‐guided micro‐printing of Prussian Blue is realized by the localized crystallization of FeFe(CN)₆ on the substrate confined by the ink meniscus and thermal reduction of the crystallized FeFe(CN)₆. This strategy is capable of being used as an electrochromic display to give real‐time directions on an augmented reality (AR) smart contact lens device.
