This work presents a wearable nanozyme-based electrochemical sensor integrated with a microfluidic patch for real-time, non-invasive sweat lactate monitoring at neutral pH. The Co₃O₄/Co₃(PO₄)₂modified screen printed electrode shows strong electrocatalytic performance, enabling a wide detection range (1–80 mM) with high sensitivity and a low detection limit (0.3 mM). The device demonstrates excellent selectivity and >91% on-body accuracy during exercise, highlighting its potential for personalized health and sports performance monitoring.
