Porous Core–Shell Yarn in Wearable Electrochemical Sensors for Real-Time Sweat Monitoring

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 19, 2024

Wearable sweat sensors have garnered substantial attention owing to their actual significance in the noninvasive and real-time monitoring of health conditions. However, it remains significantly challenging efficiently construct a high-sensitivity sensor with stable long-term sensing capability. Herein, we report an effective methodology based on wet-spinning/acid-etching technology porous core–shell yarn-based wearable electrochemical sensor. This strategy increases inductive surface area ion concentration facilitates signal transmission. As result, demonstrates high sensitivity for K+ pH (54.89 mV/dec 40.2 mV/pH pH). Furthermore, exhibit outstanding stability, good stability (>16 h), satisfactory bending resistance (>1000 cycles). More importantly, yarns could be prepared at speeds up 500 m/h continuous preparation strategy, which enabled mass fabrication Electrochemical serve as sweat-sensing systems hold great potential commercialization health-detection technology.
