Abstract

The Gx Sweat Patch is a wearable microfluidic sweat sensor that can be worn by athletes to monitor their sweating rate and sweat chloride concentration. Here, we highlight the commercialization of the Gx Sweat Patch, from developing and optimizing prototypes of a wearable sweat-sensing platform, to validation in competitive individual and team-sport athletes, and the challenges of commercial launch.
