With the slackening of fossil fuels and anxious about greenhouse gas emission culminate, the ever-expanding requirement for green renewable energy, and also to set up the energy with more efficiency. In this context, thermoelectric technology has been of great significance considering the potential growth of electrical energy to heat energy and vice versa through a thermocouple and uses the waste heat for useful purposes. However, due to its low energy efficiency, large scale production of this energy is still not resolved. People in past decades have instigated diverse techniques to exalt the efficiency of the thermoelectric materials(TE), which described with regard to the dimensionless property ZT (figure of merit). The preferment of printing methods has created TE materials printable and flexible, which thunderously distend TE material applications. Thermoelectric scaffolds are of great interest for flexible TE materials. Layered structural $\mathrm{B}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_3\mathrm{o}\mathrm{n}\mathrm{S}\mathrm{W}\mathrm{C}\mathrm{N}\mathrm{T}\mathrm{n}\mathrm{e}\mathrm{t}\mathrm{w}\mathrm{o}\mathrm{r}\mathrm{k}\mathrm{a}\mathrm{s}\mathrm{s}\mathrm{c}\mathrm{a}\mathrm{f}\mathrm{f}\mathrm{o}\mathrm{l}\mathrm{d}$ had a power factor as high as (−1600 $\mu W{m}^{-1}{K}^{-2}$ at room temperature), the thermal conductivity of (0.26 $\pm 0.03W{m}^{-1}/K^1)$ TE ZT (0.89 at room temperature). These are high-performance flexible TE materials used in wearable sensors for monitoring blood pressure, respiration rate, body temperature, and sleep period. TE materials have high electrical conductivity (about 500–1000 S/cm at room temperature (RT)) and low thermal conductivity (2–3 W m/K), which makes it suitable for different high temperature and heat applications. Currently, nanomaterials and nanosystems are used to make TE materials ascribed to its towering performance. In this review, we would like to discuss thermoelectric scaffolds – its preparation techniques, materials of interest, advantages, and applications, and finally, its future scopes. The 3D printing technique, which makes three dimensional solid objects from a digital file, is increasingly and commonly used for making TE materials having super low thermal conductivity, which also discussed in the review.

随着化石燃料的匮乏和对温室气体排放的担忧达到顶峰，对绿色可再生能源的需求不断扩大，同时也要求更高效地建立能源。在这种情况下，考虑到电能的潜在增长以通过热电偶进行加热，反之亦然，并且将废热用于有用目的，热电技术具有非常重要的意义。然而，由于其能量效率低，该能量的大规模生产仍未解决。在过去的几十年中，人们已经提出了各种技术来提高热电材料（TE）的效率，该技术针对无量纲特性ZT（品质因数）进行了描述。印刷方法的偏爱使TE材料可印刷且灵活，极大地扩展了TE材料的应用范围。热电支架对于柔性TE材料非常感兴趣。分层结构$\mathrm{乙}{\mathrm{一世}}_2\mathrm{Ť}{\mathrm{Ë}}_3\mathrm{Ø}\mathrm{ñ}\mathrm{小号}\mathrm{w\; ^}\mathrm{C}\mathrm{ñ}\mathrm{Ť}\mathrm{ñ}\mathrm{Ë}\mathrm{Ť}\mathrm{w}\mathrm{Ø}\mathrm{[R}\mathrm{ķ}\mathrm{一种}\mathrm{s}\mathrm{s}\mathrm{C}\mathrm{一种}\mathrm{F}\mathrm{F}\mathrm{Ø}\mathrm{升}\mathrm{d}$ 功率因数高达（−1600 $\mu \mathrm{w\; ^}{米}^{-\mathrm{1个}}{ķ}^{-2}$ 在室温下），导热系数为（0.26 $\pm 0.03\mathrm{w\; ^}{米}^{-\mathrm{1个}}/{ķ}^{\mathrm{1个}}）$TE ZT（室温下为0.89）。这些是可穿戴传感器中使用的高性能柔性TE材料，用于监测血压，呼吸频率，体温和睡眠时间。TE材料具有较高的电导率（室温（RT）时约为500–1000 S / cm）和较低的导热率（2–3 W m / K），因此适用于不同的高温和高温应用。当前，纳米材料和纳米系统被用于制造归因于其高耸性能的TE材料。在这篇综述中，我们想讨论热电支架-它的制备技术，感兴趣的材料，优势和应用，最后是其未来范围。3D打印技术可以从数字文件中制作三维立体物体，
