Photocurable Nanocellulose-Based Hydrogel for Real-Time Electrochemical Sweat Monitoring in Smart Textiles.

ABSTRACT: Wearable sweat sensors demand hydrogels that wet textiles rapidly, cure on demand, and retain mechanical integrity during use. In this work, a UV-curable poly(acrylic acid)/cellulose nanocrystal (PAA/CNC) hydrogel was developed to improve the performance and reliability of flexible electronic sensing systems. The formulation gels within about 2 to 4 s across the series and forms a uniform network suitable for scalable coating and patterning. CNCs simultaneously enhance hydrophilicity and mechanical robustness: the static contact angle decreases from 37.1° at 0 wt % CNC to 9.9° at 10 wt % CNC, while the equilibrium swelling ratio peaks at 657% for 8 wt % CNC and remains high at 650% for 10 wt % CNC, balancing hydrations with dimensional stability. Bulk properties improve with CNC loading, w
