The best Apple Watch can already track your blood oxygen, calories burned, and activity, but a new patent application by Apple could add a whole new dimension.
The tech tycoons at Apple have submitted an application with the US Patent and Trademark Office to help measure a user's perspiration level via electrodes beneath the device. While the application hasn't been granted, it's expected to be able to track fluid rate to help with hydration management during a workout.
Quantity and kind of sweat produced is a new metric for even the best smartwatches and most advanced fitness trackers, and has all sorts of applications while raising interesting questions such as:
- What happens when it's raining or you're swimming?
- If you wear it in the shower can it tell the difference?
- Does sleep sweat count?
Sweat tracking is a relatively recent advancement in wearable tech, but Apple wouldn't be breaking entirely new ground if its patent comes to fruition: just its on-watch implementation.
How useful would you guys find this new addition to the iWatch?
