Let them see you sweat: What new wearable sensors can reveal from perspiration
From: Berkeley News - 01/27/2016

University of California-Berkeley researchers say their flexible sensor
system is the first fully integrated electronic system that can provide
continuous, noninvasive monitoring of multiple biochemicals in sweat.
Specifically, it can measure metabolites and electrolytes in sweat, calibrate
the data based upon skin temperature, and sync the results in real time to a
smartphone. The advance opens doors to wearable devices that alert users to
health problems such as fatigue, dehydration, and dangerously high body
temperatures.
