Abstract: A wearable paper-based platform with simultaneous passive and active feedback for monitoring perspiration is provided. The sensor platform comprises two modules: a disposable wicking-based sweat collection patch with discrete colorimetric feedback, and a reusable electronic detachable module for active feedback. The disposable patch comprises a hygroscopic wicking material laminated between two polymeric films. The wicking material is patterned with a radial finger design that offers discretized visual readout of the sensor. The active module attaches to the film and alerts the user when the film collects a pre-determined volume of sweat. The multi-feedback system allows high-performance athletes who value objective quantification of perspiration to better assess their sweat loss during physical activities.
