摘　　要：随着全球能源的消耗加剧,热电器件的开发应用成为解决能源消耗问题的有效途径之一,其中,碲化铋(Bi_(2)Te_(3))基柔性热电器件因在可穿戴领域逐步实现应用,得到了学界和业界的广泛关注。然而,受其材料成本较高、刚性结构等多方面因素的限制,Bi_(2)Te_(3)基柔性热电器件难以在保持高效热电性能的同时,实现柔性可穿戴化应用。本文系统地阐述了当前Bi_(2)Te_(3)基柔性热电器件在材料复合与柔性结构设计上的研究进展,特别是在柔性结构设计上,涵盖了块状、膜类及纱线型3种结构。最后,总结分析了Bi_(2)Te_(3)柔性热电器件未来可能面临的挑战与发展趋势,以期促进热电器件在可穿戴领域实现广泛应用。As the global energy consumption increasing rapidly,development and application of thermoelectric devices have become one of the effective ways to solve the problem.Among them,bismuth telluride(Bi_(2)Te_(3))-based flexible devices attract widespread attention because they have been applied in the wearable sector gradually.However,due to the limitations of high material cost,rigid structure,and other factors,it is difficult for Bi_(2)Te_(3)-based flexible thermoelectric devices to achieve flexible wearable applications while maintaining efficient thermoelectric properties.This paper systematically reviews the current research progress of Bi_(2)Te_(3)-based flexible thermoelectric devices in terms of material composites and flexible structure design,especially in terms of flexible structure design,which covers three types of structures:Ingot-,film-and yarn-shaped.Finally,it summarizes and analyzes the possible future challenges and development trends of Bi_(2)Te_(3)-based flexible thermoelectric devices,to facilitate the realization of a wide range of applications for thermoelectric devices in the wearable field.
