Considerable thermal energy is emitted into the environment from human activities and equipment operation in the course of daily production. Accordingly, the use of thermoelectric generators (TEGs) can attract wide interest, and it shows high potential in reducing energy waste and increasing energy recovery rates. Notably, TEGs have aroused rising attention and been significantly boosted over the past few years, as the energy crisis has worsened. The reason for their progress is that thermoelectric generators can be easily attached to the surface of a heat source, converting heat energy directly into electricity in a stable and continuous manner. In this review, applications in wearable devices, and everyday life are reviewed according to the type of structure of TEGs. Meanwhile, the latest progress of TEGs' hybridization with triboelectric nanogenerator (TENG), piezoelectric nanogenerator (PENG), and photovoltaic effect is introduced. Moreover, prospects and suggestions for subsequent research work are proposed. This review suggests that hybridization of energy harvesting, and flexible high-temperature thermoelectric generators are the future trends.
在日常生产过程中，人类活动和设备运行会向环境中排放大量热能。因此，热电发电机（TEG）的应用备受关注，它在减少能源浪费和提高能源回收率方面具有巨大潜力。值得注意的是，随着能源危机的加剧，热电发电机在过去几年中受到了越来越多的关注，并得到了显著发展。其发展的原因在于热电发电机可以轻松地附着在热源表面，以稳定、连续的方式将热能直接转化为电能。在这篇综述中，根据热电发电机的结构类型，对其在可穿戴设备和日常生活中的应用进行了综述。同时，介绍了热电发电机与摩擦纳米发电机（TENG）、压电纳米发电机（PENG）以及光伏效应杂交的最新进展。此外，还对后续研究工作提出了展望和建议。这篇综述表明，能量收集的杂交以及柔性高温热电发电机是未来的发展趋势。
