How do smart bracelets collect our body data?

As a wearable device, the smart bracelet can help monitor our exercise, sleep, some diet and other data in daily life, and keep abreast of our health information through data synchronization. more and more popular. Today I will talk with you about how smart bracelets collect our body data so that you can use it better in your future life.

The smart bracelets on the market have functions such as heart rate monitoring, step count statistics, and sleep monitoring, which are all realized by relying on the internal sensors. The sensor is the core part of the smart bracelet. Taking heart rate monitoring as an example, the sensor in the smart bracelet uses the hemoglobin in the blood to absorb infrared and red light differently than oxygen and hemoglobin, collects the spectrum of the reflected light, and processes it through the internal algorithm to obtain a relatively accurate heart rate. curve.

The step count of the smart bracelet is the credit of the acceleration sensor. People will inevitably swing their arms in the process of walking. The acceleration sensor can judge whether the person is in motion through the direction of the person’s walking, the acceleration and the position of the force. The actual number of steps, in addition to the number of steps, the smart bracelet can also set other sports methods, such as running, swimming, skipping, etc. According to the different states selected by the user, the smart bracelet can provide users with accurate and accurate information according to different algorithms of the sensor. Perfect experience.

Sleep monitoring is also achieved through the same sensor technology. Human sleep can be divided into five stages according to brain wave signals: falling asleep, light sleep, deep sleep, deep sleep, and rapid eye movement. Gravitational acceleration sensing in smart sensors can determine which stage of sleep a person is in through the amplitude and frequency of people’s actions during sleep. The smart alarm clock function of the bracelet will wake up the user during the rapid eye movement period, because during the rapid eye movement period sleepers will have high-frequency and low-amplitude brain waves similar to those when they are awake, and waking up at this time will make the sleeper feel awake. Refreshing breath, achieve a good sleep effect.

The basic functions of smart bracelets are almost the same, and the sense of use is still rooted in the difference of sensors. Instead of buying different smart bracelets and comparing them one by one, it is better to customize smart bracelets. Medication reminders, calls and other functions allow you to enjoy a healthy life at all times. Syhogy (Xiamen) Tech Co.,Ltd. has rich R&D experience in the development of intelligent IoT products. It can not only customize smart bracelets, but also customize personalized intelligent health systems to protect your health in real time.
