Although the mi band 6 is still a bracelet in appearance, it can be said that the function is basically the same as that of a smart watch, which is the biggest change in the function of the mi band 6, supplementing the blood oxygen test and heart rate monitoring.
Although heart rate monitoring is not a new function on the bracelet, it can support 24-hour abnormal heart rate monitoring. When our pulse is abnormal, the bracelet will immediately give an early warning, which is not only useful for young people, but also more suitable for elderly parents at home.
In addition to heart rate monitoring, the blood oxygen function also successfully landed on the bracelet. At present, in order to take care of battery life, the blood oxygen monitoring function of mi band 6 supports single measurement and continuous measurement at night. In principle, the infrared light absorption changes of different wavelengths in human peripheral tissues are detected by PPG sensor, and the arterial oxygen saturation is calculated and estimated on this basis. This is also the mainstream detection method at present.
But don't think that's it. Hand-meter bracelet 6 has achieved "1+ 1 > 2" through blood oxygen detection and heart rate monitoring. Through blood oxygen detection and heart rate monitoring, we can successfully increase the monitoring of respiratory sleep quality, and combine the data of heart rate changes and blood oxygen changes monitored during sleep to comprehensively judge the sleep respiratory quality, which is qualitatively improved compared with the previous sleep quality monitoring.
In addition to blood oxygen detection+heart rate monitoring+respiratory sleep quality monitoring, mi band 6 also adds rapid eye movement (REM) monitoring, which can provide analysis reports according to the variability of heart rate during sleep and the changing law of respiratory information.
Not only can it be monitored when sleeping at night, but mi band 6 also optimizes the sporadic nap mode, and naps with a sleep time of not less than 20 minutes are also monitored, recorded and reported. It can be said that the health detection function has been comprehensively improved on mi band 6.
