Huawei sports bracelet adopts more scientific and professional Huawei TruSleep sleep detection technology. The monitoring principle of this technology is consistent with the cardiopulmonary coupling analysis technology proposed by Harvard Medical College, and it has passed the certification test of CDB of Harvard Medical College, so that it can judge the time and proportion of each sleep stage and accurately describe the sleep structure.
When people sleep, there is a wonderful coupling relationship between heart rate and breathing. When people fall asleep, this coupling will be enhanced. However, this coupling will also show different characteristics in light sleep, rapid eye movement or some diseases (such as sleep-disordered breathing).
Based on this discovery, in 2005, CDB of Harvard Medical College innovatively put forward the concept of cardiopulmonary coupling, abbreviated as CPC, and developed a mature technology, which can accurately give the sleep stage. Through clinical verification, these results are very consistent with the traditional sleep staging results based on EEG.
This analytical method has been certified by FDA, and can be used as a safe and effective tool for clinical sleep quality evaluation. A large number of clinical experiments in medical institutions in the United States, Europe and Asia (including China) have also proved the accuracy and reliability of CPC technology. Huawei sports bracelet is based on this technology, which makes its sleep monitoring data more accurate.
Extended data
Intelligent monitoring of sleep is generally divided into three types: mobile APP monitoring, wearable device monitoring and wearable device monitoring.
Mobile phone application monitoring. Mobile APP monitors sleep by using the acceleration sensor and gyroscope inside the mobile phone to monitor sleep action, so as to analyze sleep quality and deep sleep time. This APP will prompt you to put your mobile phone somewhere on the bed, and then start recording a series of processes from lying down to falling asleep, deep sleep and waking up according to the vibration of the bed.
Generally speaking, the functions of this kind of APP include: monitoring the time of entering sleep, monitoring the time of deep sleep, recording the function of talking or snoring during sleep, and recording the waking time. However, it is not difficult to find that in principle, mobile APP monitoring senses the vibration of the bed through the sensor of the mobile phone, which is good for singles, and there is only one person in the bed.
If it is a double bed where husband and wife sleep together, how to calculate this vibration? Moreover, there are still problems such as radiation and power consumption in monitoring with mobile APP. For people who have no direct contact with the monitored person, it is even more impossible to monitor data such as pulse and oxygen saturation.
Wearable devices. Wearable devices have their own acceleration sensors, so you can record your actions without relying on your mobile phone. Whether you wear a bracelet, watch or ring that fits your body and can move with your body, you can feel your movements more accurately through the built-in acceleration sensor.
When the acceleration sensor in the wearable device records your movement, you can send your data to the mobile phone via Bluetooth, analyze it in the mobile APP through the personal data provided by the user, such as age, and finally give a statistic in the APP. What data will be included in this statistic depends on what hardware your wearable device supports.
For example, if your wearable device has a heart rate sensor, you can record your heart changes during sleep. If there are red LEDs and infrared LEDs, you can also detect the blood oxygen content. These are helpful for your sleep monitoring, which is much more accurate than mobile phone monitoring. Moreover, wearable devices are independent and will not be affected by people who sleep together.
This measurement method is much more accurate than mobile phones, but a bracelet is far from fully knowing how your brain waves move during sleep, or accurately analyzing the reasons for your insomnia.
Non-wearable devices. Non-wearable devices usually include smart mattresses, smart pillows, smart bed belts and smart pillow buttons. This intelligent hardware product specially designed for monitoring sleep usually has a high-sensitivity sensor built in, which can record the user's sleep quality, heart rate, breathing and snoring.
Users can view the sleep report after software analysis on their mobile phones through Bluetooth connection. At the same time, most wearable smart devices that monitor sleep also have the function of playing background music to promote sleep, and there are smart alarm clocks in the morning to make it less painful for you to wake up in a light sleep.
The biggest weakness of wearable devices is the inability to record and analyze breathing, which is the advantage of non-wearable devices. Non-wearable devices can also monitor the quality of sleep according to the individual's exercise. Although it is placed on the bed, it is in close contact with people and the exercise record is more accurate.
But again, this kind of sleep monitoring can only achieve the effect of monitoring. Although it can help you analyze deep sleep, breathing, heartbeat and other data, it can't tell you exactly where the sleep problem lies. There is still a certain gap with the real sleep monitoring in the hospital. Smart wearable devices can monitor sports health, such as heart rate monitoring, blood oxygen monitoring, sleep monitoring and so on. Applewatch can also support sleep monitoring, so what does apple watch think about deep sleep?
What does applewatch think of deep sleep?
1. Open the sleep APP of AppleWatch or the health app of mobile phone, and set the sleep goal.
2, wearing a watch to sleep, Apple_atch can track and check the deep sleep situation, that is, sleep time. Open the "Sleep" App after getting up, find out how long you have slept, and check your sleep trend in the past 14 days.
This paper takes AppleWatchSeries6 as an example and applies it to WatchOS7 system.
How to use the sleep detection function of Glory Bracelet 3
When the bracelet is connected to Huawei wearable app, start scientific sleep.
1, Andriod mobile phone users: Please start the scientific sleep on the homepage of Huawei Wear app.

IOS users: Check the sleep data on the homepage of Huawei Wear app, and click details to view the detailed data.
How does smart wear monitor sleep quality?
Everyone's body always changes from going to bed to going to sleep. For the smart watch bracelet, when it is worn on the wrist while sleeping, it will inevitably produce various displacements and changes in gravity points, and the sleep monitoring function of the smart watch bracelet will record and judge whether people are sleeping. Microgram Technology has independently developed a variety of sub-health function algorithms for measuring sleep, heart rate, blood pressure and blood sugar. When users use smart wear related products, the built-in "sleep" health function algorithm in smart wear can remind users to fall asleep within a preset time, and can track the sleep situation of human body, measure the sleep quality of users, and guide users to develop healthy sleep habits.
