Apple Patent Reveals Plans for Perspiration Sensor Integration on Apple Watch for Sweat Monitoring

Apple is delving deeper into health and fitness tracking capabilities with a newly proposed sensor for its Apple Watch, aiming to revolutionize sweat measurement monitoring. The tech giant’s relentless pursuit of innovation in wearable technology has led to the development of this groundbreaking sensor, poised to offer users unparalleled insights into their perspiration metrics.

With previous rumors suggesting the integration of a blood pressure sensor in the upcoming Apple Watch Series 10, the company’s commitment to advancing health monitoring features is evident. The patent application, titled “Wearable devices with perspiration measurement capabilities,” recently surfaced at the US Patent and Trademark Office, shedding light on Apple’s ambitious plans.

According to the application, the proposed sensor may employ two distinct electrodes to accurately measure perspiration levels, paving the way for enhanced health tracking capabilities. As Apple continues to push the boundaries of wearable technology, users can anticipate a future where their Apple Watch seamlessly integrates advanced health monitoring features to empower them on their wellness journey.

Apple could employ perspiration measurement sensors in multiple ways. The most likely way would be to track the rate of loss of sweat, which could provide insight into the hydration level of a user. The iPhone maker may use this to send alerts for dehydration. The rate of perspiration can also be used to determine the amount of sodium lost by the body, which may prompt the smartwatch to notify the user about possible hyponatremia. In contrast, a lack of sweating can lead to turbulent body heat regulation, and an early warning could help the user get medical help to diagnose the underlying reason.

However, this is also noted that not all patent applications result in approved patents. On top of that, Apple already holds a large number of patents that are yet to be turned into commercial features. As a result, it is currently unclear whether users will see such a feature rolled out with the a future Apple Watch model.

While the perspiration sensor is unlikely to make its debut on Apple’s upcoming smartwatch model, an earlier report suggested that the Apple Watch Series 10 — expected to arrive later this year — might be equipped with blood pressure monitoring and sleep apnea detection features. Bloomberg’s Mark Gurman claimed that Apple has been working on these features for quite some time, and they could finally be rolled out on the company’s 10th generation smartwatch.
