However, achieving prolonged and reliable sweat sampling, along with stable biochemical analysis, remains challenging due to inconsistent secretion, rapid evaporation, and the reliance on external stimulation. Here, we present BMS\n                    <jats:sup>3<\/jats:sup>\n                    , a bioinspired microfluidic wearable sweat sensor system designed for multiday continuous metabolic monitoring.

A miniaturized carbachol gel\u2013based iontophoresis module autonomously induces localized sweat secretion. Furthermore, the microfluidic design sustains sweat sampling for over 2 days from a single iontophoresis session, eliminating the need for physical exertion.
