Abstract Though visualizing perspiration constituents is crucial for physiological evaluation, inadequate material healing and unreliable power supply methods restrict its applications. Herein, a fully flexible self‐powered sweat sensor fabricated from cellulose‐based conductive hydrogel to address these issues. The electrode composed of cellulose nanocomposite polymerized in situ with polyaniline cross‐linked polyvinyl alcohol/borax. nanocomposites furnish the tensile electrical self‐healing efficiencies exceeding 95% within 10 s, stretchability 1530%, conductivity 0.6 S m −1 . quantitatively analyzes Na + , K Ca 2+ contents perspiration, sensitivities 0.039, 0.082, 0.069 mmol –1 respectively, real time via triboelectric effect wirelessly transmits results user interface. This high flexibility, stability, analytical sensitivity selectivity provides new opportunities health monitoring.
