The heart is called the "pump of life" and is one of the most important organs in the human body. Heart health is very important to the health of life. In recent years, the incidence of cardiovascular diseases has risen rapidly, which has caused great danger to human health. Therefore, heart problems have become one of the health problems that people pay close attention to. ECG signals can reflect the health of the human heart, and there are many types of ECG monitoring equipment on the market.

Bracelet-type (watch-type) ECG equipment is the most common ECG monitoring equipment in daily life. PPG photoplethysmography technology is usually used to detect the intensity of reflected light absorbed by human blood and tissues by photoelectric sensors, and to trace blood vessels. Changes in the cardiac cycle to calculate the heart rate; this technology can perform simple normalized real-time detection, but the light emission is easily affected by the surrounding environment such as skin color and dryness of the skin surface, resulting in errors and low accuracy in the detection results good. The patch-type ECG device uses two electrodes to collect point signals from the skin on the chest of the human body to obtain the human body's ECG. It can be pasted on the human body for long-term monitoring, but it will bring inconvenience to life. When it is not in use, it needs to be stored and carried extra, which brings difficulties to the real-time and timely monitoring of human ECG.
