Camouflage: Protochromic Devices from a Cephalopod Structural Protein (advanced Optical Materials 20/2017)

In article number 1600751, Alon A. Gorodetsky and co-workers describe color-changing devices that are inspired by the constituent components of optically-active ultrastructures found in cephalopod skin cells. These devices are electrically controlled and exhibit distinct shifts in their reflectance and coloration due to the injection/extraction of protons. The findings hold significance for developing novel camouflage technologies, understanding ion-transporting biological systems, and engineering improved bioelectronic platforms.
