The next iteration of Apple Watch, the tech giant’s popular wearable offering, could help the wearer check if they are dehydrated.
Apple was earlier this week granted a patent in this regard by the US Patent and Trademark Office.
In the patent, filed in 2018, Apple has claimed: “A watch can be positioned to receive and measure one or more electrical properties of perspiration produced by the user wearing the watch.”
It went on to add: “The electrical properties, such as electrical conductance, can represent a concentration of electrolytes in the perspiration, which in turn represents a hydration level of the user.”
The measurements are expected to be taken via electrodes placed within the band of the Apple Watch.
Thus, the hydration-tracking can be “performed non-invasively, repeatedly, accurately, automatically, and with minimal user intervention,” said Apple in the patent.
It also said: “The measurements can be used to provide useful feedback and health tracking information to a user, thereby allowing the user to better manage hydration and overall health.”
With temperatures rising globally, and more so in the Gulf countries, this could be a useful feature for users of this Apple device.
