- New technology from Apple could measure levels of electrolytes in perspiration.
A new Apple Watch patent reveals an Apple Watch could one day measure user hydration by measuring the electrolytes in your sweat.
A new patent for Apple published today is titled 'Hydration measurement with a watch' and its abstract states:
The new patent would be designed to monitor hydration and dehydration in the context of both sporting performance and general health in tandem with current measurements like heart rate and blood oxygen monitoring. The system works by measuring the electrical properties of sweat, correlating the measurements with a concentration of electrolytes in the sweat and using this to determine hydration.
Just an idea on paper, this technology definitely won't be around for Apple Watch Series 7, but could one day debut in an Apple Watch of the future to build on the device's pretty excellent health monitoring capabilities.
