I always heard that if you feel thirsty you are already dehydrated. This wearable will tell you when its time to drink more Gatorade. Seems like there is a little bit of a conflict of interest but a nifty idea anyway.
Via Gizmodo:
Developed by a startup called Epicore Biosystems working with PepsiCo’s Gatorade subsidiary, the new Gx Sweat Patch (featuring Gatorade’s recognizable branding) is designed to be stuck to the inner left arm of an athlete during a workout. An accompanying app generates a “sweat profile” that lets the wearer know how much to drink to replenish their hydration levels.
During a workout, sweat emanating from the wearer’s skin makes its way into one of the channels and slowly fills it up while it’s dyed orange (using non-toxic food dyes) in the process to make its progress more visible. In a separate channel, chemicals react with chlorine in the sweat and turn purple, indicating the concentration of sodium detected, which is then used to determine the wearer’s electrolyte balance.
