Abstract | Wearable thermoelectric generators (TEGs) are considered as a promising power supply for low power wearable electronics. To obtain high thermoelectric (TE) generation, the focus should be on two main factors, including TE materials and the configurations of TE legs. Concerning these two factors, this paper provides a comprehensive review of recent studies on wearable TEGs. In general, TE materials can be classified into three categories, including inorganic, organic, and hybrid (inorganic-organic). In addition, the TE legs can be prepared in three different configurations, including ingot-shaped, film-shaped, and yarn-shaped. Based on the reviewed literatures, the superior output powers of all the three configurations were achieved by the inorganic, hybrid, and organic TE materials, respectively. It should be noted that the ingot- and the yarn-shaped legs were mostly composed of the inorganic and the organic TE materials, respectively. Whereas, all the three types of TE materials were almost equally used to prepare the film-shaped legs. Regarding power density, the ingot-shaped legs stood first followed by the film- and the yarn-shaped legs, respectively. Precisely, the output powers of the ingot- and the film-shaped legs were at µW/cm2 level, dropping to nW/cm2 for the yarn-shaped legs. |
