柔性热电材料在智能可穿戴设备中发挥着重要作用，如可穿戴发电、自供电传感和个人热管理。然而，随着物联网（IoT）和人工智能（AI）的快速发展，对可穿戴电子产品的舒适性、多功能性和可持续运行性提出了更高的标准，而要满足目前报道的热电器件的所有要求仍然具有挑战性。在此，我们提出了一种基于热电针织面料的多功能、可穿戴、无线传感系统，其透气性超过600 mm·s^-1，可拉伸性达到120%。该器件配合无线传输系统，可以通过手机应用程序（APP）实现对人体呼吸的自供电监测。此外，还设计了集成热电系统，将光热转换和被动辐射冷却相结合，实现了太阳能驱动面内温差供电并通过APP监测室外阳光强度。此外，我们还根据针织物的各向异性，解耦了太阳照射下变形过程中电阻和热电压的复杂信号，使器件能够通过APP监测和优化运动员的户外身体活动。这种新型的基于热电织物的可穿戴和无线传感平台在下一代智能纺织品中具有广阔的应用前景。

Flexible thermoelectric materials play an important role in smart wearables, such as wearable power generation, self-powered sensing, and personal thermal management. However, with the rapid development of Internet of Things (IoT) and artificial intelligence (AI), higher standards for comfort, multifunctionality, and sustainable operation of wearable electronics have been proposed, and it remains challenging to meet all the requirements of currently reported thermoelectric devices. Herein, we present a multifunctional, wearable, and wireless sensing system based on a thermoelectric knitted fabric with over 600 mm·s⁻¹ air permeability and a stretchability of 120%. The device coupled with a wireless transmission system realizes self-powered monitoring of human respiration through an mobile phone application (APP). Furthermore, an integrated thermoelectric system was designed to combine photothermal conversion and passive radiative cooling, enabling the characteristics of being powered by solar-driven in-plane temperature differences and monitoring outdoor sunlight intensity through the APP. Additionally, we decoupled the complex signals of resistance and thermal voltage during deformation under solar irradiation based on the anisotropy of the knitted fabrics to enable the device to monitor and optimize the outdoor physical activity of the athlete via the APP. This novel thermoelectric fabric-based wearable and wireless sensing platform has promising applications in next-generation smart textiles.
