Advances of electrochromic and electro-rheological materials

Abstract This chapter discusses the main advances in electrochromic and electro-rheological materials. First are presented the different types of chromogenic materials, of which the electrochromic (EC) materials are an example, and the main factors that influence the performance of these materials. Electrochromic devices (ECDs) are a potential application of EC materials and the components of these devices are also discussed. Finally, different types of EC materials are presented and their main features are discussed. In electro-rheological (ER) materials, their definition and main components are presented. The different types of ER materials and some examples are shown here. Also the critical parameters that influence the ER effect are discussed. Finally, some applications of these materials are presented.
