Electrochromic materials are substances that reversibly change their optical properties, such as color or transparency, when an electrical voltage is applied. This change is typically caused by redox reactions that alter the material’s electronic or structural state.
Key features of electrochromic materials include:
Durability over many switching cycles
Common applications include:
Wearable electronics and adaptive camouflage
Materials widely used in electrochromic devices include metal oxides (like tungsten oxide, WO₃), conductive polymers (like PEDOT), and transition metal complexes.
