Thermoelectric (TE) materials have the capability of converting heat into electricity, which can improve fuel efficiency, as well as providing robust alternative energy supply in multiple applications by collecting wasted heat, and therefore, assisting in finding new energy solutions. In order to construct high performance TE devices, superior TE materials have to be targeted via various strategies. The development of high performance TE devices can broaden the market of TE application and eventually boost the enthusiasm of TE material research. This review focuses on major novel strategies to achieve high‐performance TE materials and their applications. Manipulating the carrier concentration and band structures of materials are effective in optimizing the electrical transport properties, while nanostructure engineering and defect engineering can greatly reduce the thermal conductivity approaching the amorphous limit. Currently, TE devices are utilized to generate power in remote missions, solar–thermal systems, implantable or/wearable devices, the automotive industry, and many other fields; they are also serving as temperature sensors and controllers or even gas sensors. The future tendency is to synergistically optimize and integrate all the effective factors to further improve the TE performance, so that highly efficient TE materials and devices can be more beneficial to daily lives.

Thermal energy harvesting from the ambient environment through thermoelectric nanogenerators (TEGs) is an ideal way to realize self‐powered operation of electronics, and even relieve the energy crisis and environmental degradation. As one of the most significant energy‐related technologies, TEGs have exhibited excellent thermoelectric performance and played an increasingly important role in harvesting and converting heat into electric energy, gradually becoming one of the hot research fields. Here, the development of TEGs including materials optimization, structural designs, and potential applications, even the opportunities, challenges, and the future development direction, is analyzed and summarized. Materials optimization and structural designs of flexibility for potential applications in wearable electronics are systematically discussed. With the development of flexible and wearable electronic equipment, flexible TEGs show increasingly great application prospects in artificial intelligence, self‐powered sensing systems, and other fields in the future.

“…Further increase of SDBS or PEI loading leads to thicker coating layers ( Figure S2, Supporting Information). [29] Moreover, X-ray photoemission spectroscopy (XPS) further verify the doping effectiveness ( Figure 1B). All display a strong band at ≈1594 cm −1 (G band) and a very weak band at ≈1348 cm −1 (D band), confirming that after being organically chemical doped by either SDBS or PEI, the high crystallinity of the pristine SWCNT is well reserved, and no obvious defects are introduced.…”

“…In essential, the assembly modes can be divided into three major strategies, namely, (b) serial, (c) folding, and (d) stacking routes. [28][29][30] Regretfully, it is impossible to make direct comparison and effectively evaluate the assemble strategies among these flexible TE devices, since various parameters defining the device output performance are different, for example, the materials' TE performance of the p-and n-unit films, the film dimensions (length, width, and thickness), the number of p-n couples (N), and even the applied temperature gradients between the hot end and the cold end (ΔT = T hot − T cold ). [25][26][27] In Scheme 1c, the folding-type devices are achieved by rolling the continuous flexible film of alternating p-n units on insulate plastic membrane.…”

Although organic and composite thermoelectric (TE) materials have witnessed explosive developments in the past five years, the research of flexible TE devices is rather limited. In particular, their assembly strategies and device performance reported in the literature cannot be directly compared, due to a variety of deviances including p‐ and n‐type component materials, shape and dimensions of p‐n flexible films, and applied temperature gradient (Δ T ). Here, three types of assembly strategies for flexible TE devices, that is, serial, folding, and stacking, are compared by fixing the corresponding experimental parameters. Furthermore, a convenient and general method to evaluate the flexible device performance (FDP) is put forward, that is, , where the maximum output power ( P max ) is divided by product mass ( m ), Δ T , and pair number of p‐n couples ( N ). The FDPs for the present serial, folding, and stacking devices are 11.13, 8.87, and 0.05 nW g −1 K −1 , respectively, confirming that the serial configuration is the best among the three strategies for flexible device fabrication. The preliminary evaluation method proposed herein will pave the way for a design strategy of flexible TE devices and speed up their applications in waste‐heat harvesting, e‐skin, wearable electronics, etc.
