rt rate measurement has become a common feature in smartphones. You can measure your heart rate by placing your finger on the device's camera or on a sensor. Some smartphones now come with dedicated heart rate sensors that can measure your heart rate anytime and anywhere. However, the accuracy of heart rate measurement on smartphones has been a topic of debate. While some studies suggest that smartphone-based heart rate monitors are generally accurate, the results can still vary based on factors such as skin color, ambient light, and physical activity. One study conducted by the University of California, San Francisco, found that smartphone-based heart rate monitors were almost as accurate as professional-grade medical devices. The study analyzed the heart rate measurements of 51 participants using both a smartphone-based monitor and a medical-grade monitor. The researchers found that the difference between the two devices was less than 2%. However, another study conducted by the Cleveland Clinic found that smartphone-based heart rate monitors are highly unreliable during exercise. The study analyzed the heart rate measurements of 50 participants using a smartphone-based monitor and an ECG monitor. The researchers found that the difference between the two measurements was as high as 20 beats per minute during exercise. Moreover, factors such as skin color, ambient light, and physical activity can also affect the accuracy of heart rate measurement on smartphones. For example, people with darker skin may have more difficulties when it comes to smartphones measuring their heart rate. In conclusion, while smartphone-based heart rate monitors can be accurate, their reliability can still vary. If you need to monitor your heart rate for medical reasons, it is still best to use professional-grade medical devices. But for general fitness tracking, smartphone-based heart rate monitors can provide useful insights into your heart rate and overall fitness.手机可以测心率吗 苹果手机怎么测试心率
