Apple has been granted a patent for new technology that would allow future Apple Watch models to measure the rate and total fluid loss of sweat during a workout. The patent, titled “Wearable Devices with Perspiration Measurement Capabilities,” describes the incorporation of electrodes into the Apple Watch sensor array to create a hybrid sensor for both ECG and perspiration readings. This new technology would provide users with real-time information about their sweat rate and fluid loss, as well as contextual information such as body temperature and local humidity. The Apple Watch would also take into account external factors like ambient temperature and humidity to provide accurate data.
If implemented, future Apple Watch models would be able to calculate the estimated sweat rate of a user and show metrics such as average fluid ounces lost per hour or in total. Additionally, the watch would be able to display instantaneous sweat rate from the last 15-30 seconds during a workout. This technology could be especially useful for athletes and fitness enthusiasts as it would provide valuable information for hydration and performance during physical activity. The patent suggests that Apple is focused on enhancing the fitness capabilities of its smartwatch, and the incorporation of a perspiration sensor aligns with this goal. This new feature could give Apple a competitive edge in the fitness wearables market and further solidify the Apple Watch as a comprehensive fitness tracker.
The concept of a perspiration sensor in the Apple Watch is still speculative, as many patented technologies never come to fruition. However, if Apple were to integrate this technology into future models, it could provide users with an innovative and comprehensive way to monitor their hydration and performance during workouts. Apple’s focus on fitness in recent years has been evident, and the addition of a perspiration sensor would further demonstrate the company’s commitment to enhancing the health and wellness features of its products. Overall, the patent suggests that Apple is considering new and advanced features for the Apple Watch that could potentially revolutionize the way users track their fitness and performance.
