Conducting polymer-based thermoelectric materials are considered the most promising candidates for applying to wearable thermoelectric devices because of their high electrical conductivities, flexibility, stability, and low-toxicity features. Therefore, a timely review is needed to comprehensively overview their most recent progress in the last few years, considering the rapid development of thermoelectric conducting polymers. In this work, we carefully summarize recent advances in thermoelectric conducting polymers from aspects of their mechanisms, synthesis, micro/nanostructures, mechanical/thermoelectric properties, and related functional devices. A few state-of-theart thermoelectric conducting polymers, including poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate), poly(3-hexylthiophene), polyaniline, and polypyrrole, are highlighted in detail. In the end, we point out the challenges, controversies, and outlooks of conducting polymers for future thermoelectric applications.

“…In addition to pure PEDOT: PSS thin films, the hybrids of organic and inorganic materials have improved TE performance. For example, a thin-film material with high crystallinity was obtained by combining Bi 0.5 Sb 1.5 Te 3 (BST) and PEDOT: PSS [204] . Figure 8G is a TEM image of BST-modified PEDOT: PSS.…”

“…The generator produced an output voltage of 45.2 mV and output power of 375 μW at a temperature difference of 60 K [ 89 ]. The PEDOT:PSS fibers, prepared by a continuous wet-spinning process, were treated with sulfuric acid, which had effective modulation on composition and chain conformation, as shown in Figure 5 a,b [ 96 ]. Under optimal conditions, PEDOT: PSS fibers delivered a Seebeck coefficient of 19.2 μVK −1 and a power factor of 147.8 μWm −1 K −2 [ 96 ].…”

With the rapid development of wearable electronics, looking for flexible and wearable generators as their self-power systems has proved an extensive task. Fiber-based thermoelectric generators (FTEGs) are promising candidates for these self-powered systems that collect energy from the surrounding environment or human body to sustain wearable electronics. In this work, we overview performances and device structures of state-of-the-art fiber-based thermoelectric materials, including inorganic fibers (e.g., carbon fibers, oxide fibers, and semiconductor fibers), organic fibers, and hybrid fibers. Moreover, potential applications for related thermoelectric devices are discussed, and future developments in fiber-based thermoelectric materials are also briefly expected.

The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and may therefore be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many protective equipment, thermal stress remains one of the most frequent physical hazards in many work sectors. However, many of these problems can be overcome with the use of smart textile technologies that enable intelligent thermoregulation in personal protective equipment. Smart textiles can detect, react and adapt to many external stimuli. Interconnected sensors and actuators that interact and react to existing risks can provide the wearer with increased safety, protection and comfort. Thus, the skills of smart protective equipment can contribute to the reduction of errors and the number and severity of accidents in the workplace, and thus promote improved performance, efficiency and productivity.This review provides an overview and opinions of authors on the current state of knowledge on these types of technologies by reviewing and discussing the state of the art of commercially available systems and the advances made in previous research works.
