There are plenty of wearble technologies that can help you exercise better. It is no secret that sweat provides us with a wealth of information about our body’s condition. UC Berkeley engineers have come up with a portable, wearable device that detects sweat on a user’s skin and uses various sensors to analyze different chemicals.
This sweat sensor has flexible electronics to detect different chemicals in the user’s sweat (Sodium, Potassium, Lactate, and Glucose). The data can be transmitted to a phone for further analysis. The above video provides more information on this wearable.
