Review on Wearable Thermoelectric Generators: From Devices to Applications

Wearable thermoelectric generators (WTEGs) can incessantly convert body heat into electricity to power electronics. However, the low efficiency of materials, tiny terminal temperature difference, rigidity, and neglecting optimization lateral transfer preclude WTEGs from broad utilization. In this review, we aim comprehensively summarize state-of-the-art strategies for realization flexibility high normalized density in by establishing links among TE performance, advanced design (structure, heatsinks, thermal regulation, analysis, etc.) based on inorganic bulk materials. Each section starts with a concise summary its fundamentals carefully selected examples. end, point out controversies, challenges, outlooks toward future development wearable devices potential applications. Overall, review will serve help materials scientists, electronic engineers, particularly students young researchers, selecting suitable
