BPN879: A Wearable Impedance-Based Microfluidic Sensor for Sweat Rate Monitoring

A flexible and wearable sensor is presented for real-time monitoring of localized perspiration rate of human subjects. These sweat rate measurements are validated through controlled syringe pumping and a commercial sweat collector. Real-time on-body perspiration rate evaluation of human subjects is performed through cycling experiments to examine the change in sweat rate with different power output. Since it has been shown that the concentrations of a large number of sweat biomarkers are strongly related to the variation of a subject's perspiration rate, this platform is anticipated to facilitate an accurate analysis of sweat biomarkers and provide insightful information regarding an individual's health state.
