- Apple has applied for a patent for the Apple Watch’s moisture tracking sensor system.
- The sensor will sample the electrolytes in the wearer’s sweat and calculate its level of hydration.
- This is especially useful for athletes or people who often forget to hydrate.
Hydration tracking is a standard feature of several smartwatches, allowing users to track their fluid intake. But a new Apple patent indicates that Apple Watch may soon automatically monitor the wearer’s moisture content.
be found Patent Apple (HT GizmoChina), this patent A non-invasive hydration tracking sensor is introduced in detail, which will use electrodes to monitor the electrolytes in the wearer’s sweat. The watch can calculate the user’s hydration level based on the concentration of these electrolytes in the wearer’s sweat. Apple is considering placing “one or more electrodes” on the strap of the Apple Watch.
Apple Watch moisture tracking: advantages
For athletes who are at risk of dehydration during a marathon or hiking, moisture tracking will be a convenient tool. If the hydration level drops, then the wearable device is likely to advise its owner to drink good water before dehydration begins. Although there are a large number of water reminder apps available, they rely on pre-determined time to send out reminders, rather than real-time data. When used with other indicators of the Apple Watch, hydration data can help the wearer understand their current and long-term health.
The last important sensor Apple added to its wearable product line brings ECG to Series 4. Since then, companies such as Samsung and Fitbit have also introduced body composition sensors and EDA sensors into their devices.
According to the filing date, Apple has worked on this patent for at least three years, but the sensor is unlikely to be used in Apple Watch Series 7. However, the possibility of introducing it into future models is not ruled out.
