Sweat analysis has received significant attention recently because collection of sweat is
minimally-invasive, and it contains a panel of physiologically relevant biomarkers. While
there is a significant progress in engineering sensor systems for sweat analysis, a few major
challenges remain unaddressed, eg contamination due to skin surface, old sweat mixing
with new sweat, loss of sweat due to evaporation, and dilution of analytes on excessive
sweating. To address some of these challenges, we present a wearable biosensor patch for …
