"Only professional athletes need to monitor heart rate", this is a common myth among many people. With the popularization of wearable devices, more and more users are mastering their own physiological data through smart watches, among which the most widely used function is "heart rate sensing". But how does heart rate data help people in their daily lives? In fact, knowing the heart rate at any time can not only help you understand your physical condition in real time, but also evaluate the appropriate intensity during exercise and find the most effective and safe way to exercise. According to the forecast of the research institute IDC , the global wearable device market shipments will reach 124.9 million in 2018, an increase of 8.2% over 2017. Consumers' preference for wearable devices has clearly shifted to smart watches with full functions.
At present, the industry generally focuses on " The development direction of "Health Tracking" is to develop technologies for sensing various physiological data, and then launch application functions such as heart rate, pulse oxygen, and stress index. However, in the face of the above-mentioned dazzling array of health indicators, as a consumer, do you really fully understand it? There are many products that can measure heart rate, and the price is very different. wedding photo retouching services "Accuracy" is the key to purchasing Many clinical medical studies have confirmed that monitoring heart rate can not only improve exercise performance and training efficiency, but also prevent potential health problems before they occur. Although there are many wearable devices on the market that claim to measure heart rate,
the accuracy is uneven. Recently, there have been many discussions on the Internet comparing the accuracy of various smart device manufacturers, which shows that the accuracy of data is highly valued. "Optical heart rate sensing" is one of the sensing technologies used in wearable products. It can make use of the characteristics of different oxygen content of hemoglobin in the blood, and different degrees of absorption and reflection of light. The user's wrist penetrates the skin to detect changes in blood flow and collect reflection data to accurately estimate the heart rate. Wide editing picture 2 Photo Credit: Garmin
