A flexible all‐solid‐state electrically tunable photonic crystal (ETPC) is realized by Jungyul Park and Hyung‐Kwan Chang (article number 1800792 ) through coaction of chemically induced polymer swelling and lattice control based on electric potential. The proposed ETPC mimics the mechanism of the camouflaging skin of a chameleon: the distance change between nanocrystals in the skin of chameleons induces rapid and fully reversible color changes.
