Abstract

With the advent of the information age, wearable thermoelectric fabric devices have garnered significant attention for their ability to harness environmental waste heat and body heat to supply convenient, reliable, and environmentally friendly electricity for next-generation wearable electronics. However, the complex production process and unstable power supply restrict their development. Here, we report a high-performance flexible, dependable, and wearable p-type thermoelectric device consisting of silk threads/polyaniline/amino multiwalled carbon nanotubes through dyeing process. By optimizing the weaving structure and simple assembly, this p-type fabric device generates a voltage of 0.749 ± 0.003 mV, a maximum power of 0.326 ± 0.007 nW, and a power density of 1087.532 ± 22.985 nW·m⁻² at a temperature difference of 90 ℃. Besides, this device also possesses an excellent photo-thermoelectric conversion capability and the assembled fabric bracelet can generate an output voltage of approximately 6.1 mV outdoors when worn on the hand of the experimental personnel. This fabric device also exhibits a superb reliable property even after 5000 times of folding. This strategy makes it easy to manufacture a thermoelectric fabric device on a large scale and provides a promising way for wearable electronics.

一种p型热电织物供电装置制造方法及图纸

随着信息时代的到来，可穿戴式热电织物设备因能够利用环境余热和人体热量，为下一代可穿戴电子产品提供方便、可靠、环保的电力而备受关注。然而，复杂的生产过程和不稳定的电源限制了它们的发展。在这里，我们报道了一种高性能、柔性、可靠、可穿戴的p型热电装置，该装置由丝线/聚苯胺/氨基多壁碳纳米管通过染色工艺组成。通过优化织造结构和简单的装配，该p型织物装置在温差为90℃时产生的电压为0.749±0.003 mV，最大功率为0.326±0.007 nW，功率密度为1087.532±22.985 nW·m−2。此外，该装置还具有优异的光热电转换能力，装配好的织物手环佩戴在实验人员手上，在室外可产生约6.1 mV的输出电压。这种织物装置即使在折叠5000次后也表现出极好的可靠性能。该策略使热电织物器件的大规模制造变得容易，为可穿戴电子产品提供了一条有前途的途径。

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
