1, Huawei Smart Watch
Huawei WatchD uses a miniature pressurized air pump. The principle of measurement is to pressurize the cuff until the blood flow of brachial artery is blocked, and then slowly decompress it. With the help of the instrument, the tiny pulse transmitted from the arm to the cuff is recognized, and finally the blood pressure value is obtained. On the basis of measuring blood pressure, blood pressure screening is realized by combining PPG monitoring and hybrid algorithm.
2. Huami
Yuewo GTR3Pro is equipped with PumpBeats blood pressure monitoring engine developed by Huami, which uses photoelectric sensors to monitor the changes of users' blood pressure, and then further screens blood pressure through the analysis of blood pressure data. Huami is the first brand in China to monitor blood pressure with photoelectric sensors and actually land.
smartwatch
Smart watches are watches that have information processing capabilities and meet the basic technical requirements of watches. In addition to indicating time, smart watches should also have one or more functions such as reminding, navigation, calibration, monitoring and interaction. Display methods include pointers, numbers, images, etc.
Smart watches, a wearable device, can choose products according to brands when the budget is determined, saving time and effort. Big brands that can exist in this field for a long time have long-term technical precipitation, quality control will be relatively stable, after-sales service will be guaranteed, and the probability of rollover will be relatively small.
