Abstract

In article number 1901932, Inkyu Park, Junsuk Rho and co-workers introduce a tunable Fabry–Pérot resonator that has metal–(chitosan-based hydrogel)–metal structure. The chitosan swells in response to changes in relative humidity; this change affects transmissive structural color of the multilayer structure. As demonstration, this tunable resonator is utilized for a real-time colorimetric humidity sensor combined with a photovoltaic cell, which can lead to development of a self-powered sensor.
