Abstract Wearable sweat sensing technologies have received wide attention for personalized health monitoring with continuous and molecular‐level insight in a noninvasive manner. However, it remains significantly challenging to simultaneously capture sufficient volume of achieve stable contact between electrodes sweat, especially relatively mild sweating condition. Herein, wearable electrochemical fabric sensor is developed by embroidering diversified yarns multi‐ply cotton sheath carbon nanotube‐based fiber core into super‐hydrophobic substrate. The device allows enrichment among the core–sheath yarn reduce ineffective diffusion, thus remarkably increasing efficiency. As result, only 0.5 µ L needed circuit connectivity, 1/20 lowest reported date. also maintains highly durable performance, obtained even during dynamic deformation processes such as bending, twisting, shaking. It can be further designed an integrated sports shirt system, which perform real‐time multiple chemical information (e.g., glucose, Na + , K pH) users at states both intense exercise conditions badminton like walking eating.
