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