First, the photoelectric transmission measurement method mainly uses the principle of blood light transmission. Under normal circumstances, the beating of the human heart will actually make the blood light transmittance have a certain defense. The information generated by this change will become an electrical signal under the action of the smart bracelet, and then the heart rate information can be reflected by the electrical signal. By adding a photosensitive receiver to the bracelet, the change of heartbeat can be better monitored.

Moreover, under certain conditions, the blood circulation remains relatively constant, but when the heartbeat is accelerated and the blood circulation in the body is accelerated, then the photosensitive receiver on the smart bracelet can receive more light energy. When the light intensity perceived by the smart bracelet is large, it means that the heartbeat is accelerated, so specific data can be displayed.

Second, the ECG detection method This detection method is actually the same as the ECG detection in the hospital. When people's mood fluctuates and their heart beats faster, in fact, the atria and ventricles will become more excited, so the activities of myocardial cells will also accelerate. Then the smart bracelet can detect the ECG signal by detecting the activity of myocardial cells, because the irregular movement of myocardial cells can change the potential, and this ECG signal is the detected heart rate data.

In fact, it is also a healthy way to detect heart rate with smart bracelets. After all, if there is no data showing your heartbeat, your feelings are still not accurate. Sometimes I feel my heart beating fast, but the displayed data are within the normal range. But sometimes I feel my heartbeat is normal, but the ECG data is abnormal.

Wearing a smart bracelet with you can monitor your heart health 24 hours a day, not only your heart condition, but also your sleep quality. It is a very practical product.
