Track your health with sensor integrated into smartwatch? No sweat

A team of NUS researchers has created a colour changing pH sensor that can tell if the user is dehydrated, low on sugar or a risk of skin infection, by measuring how acidic or alkaline the sweat is, using less than a drop of sweat. The sensor can be integrated easily into existing fitness trackers and smartwatches at a low cost.
