Structural color filtering has recently demonstrated great advantages over conventional colorant pigments in terms of higher resolution, sustainability, and near-permanent life time. Tunable color filters have been realized by the use of mechanical deformation, liquid crystals and chemical reaction. The latter is accomplished through change in thickness of soft protein layer in response to a small alteration of environmental cues. Special attention should be given to material selection, structural design and the dynamic color mechanism for tunable coloration using chemical reaction. Here we would like to introduce our significant effort towards application of biodegradable chitosan film in the design of cost-effective, biocompatible, and tunable metal−insulator−metal (MIM) resonators. Applying the proposed tunable Fabry-Perot interferometer to humidity sensor combined with a solar cell, we successfully demonstrate tunability of our proposed MIM filter. |
