Human sweat-based wearable glucose sensor on cotton fabric for real-time monitoring

Abstract In this work, a human sweat-based wearable sensor for real-time glucose monitoring has been fabricated on cotton substrate after treating it with two-step polymerization of pyrrole. The pyrrole-treated fabric was coated solution copper sulphate pentahydrate to grow Cu layer. cotton/pyrrole/Cu treated the solutions acetate and manganese form Cu–Mn transition-metal alloy via electrochemical deposition technique. Results indicate that developed is reliable detection limit 125 µM 378 µM. addition, output ranged between 50 400 coefficient correlation, R 2 = 0.983, indicating linear range current. sensor's response not significantly affected by interferents. also validated sweat satisfactory results.
