Flexible Thermoelectrics Based on Poly(3,4‐Ethylenedioxythiophene)

In the era of ubiquitous power consumption, thermoelectric (TE) materials offer a sustainable way to recover power by converting heat to electricity and vice versa. During the past decade, numerous remarkable progresses have been made to attain a variety of high-performance TE materials including some conducting polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT). Flexible electronic devices especially on integration with TE modules for modern wearables applications are gradually gaining traction in the recent years. In this chapter, we start with a broad introduction to flexible electronics and outline the fundamentals of TE materials and devices. Subsequently, we summarize the recent development of TE PEDOT:PSS composites and their applications for flexible thermoelectrics, and also highlight present challenges and tremendous opportunities in flexible thermoelectrics domain in the last part of the chapter.
