Wearable systems for measuring sweat rate and methods of using the same

Fabien Patrick Wildhaber, Junrui Zhang, Hoël Maxime Guérin

Presented herein are systems and methods for measuring sweat rate of a subject using a wearable system. A sweat rate may be determined automatically based on one or more signals produced by a wetting sensor module in response to a presence of sweat in the ...
