Abstract

Sweat Biomarkers In article number 2502655, Farnaz Lorestani, Amir Sheikhi, Huanyu Cheng, and co-workers present a flexible, cost-effective wearable sweat-sensing patch that enables near-real-time detection of biomarkers during low-intensity daily activities. By integrating a granular hydrogel scaffold with a microfluidic device and a highly sensitive LIG-based biosensor, the system enhances sweat uptake and storage at rest, achieving transport rates over ten times higher than those of previous designs and enabling accurate, continuous lactate monitoring.
