Design of LED Heart Rate Monitoring Circuit and Costume Bonding Position of Electrocardiography Monitoring Clothing
In order to meet the growing health needs of people, wearable multi-physiological parameter monitoring technologies were applied to the design of clothing to monitor physiological conditions in real time. In this paper, the physiological monitoring technique such as Electrocardiography (ECG) monitoring was used. The physiological basis of ECG monitoring, including the concept of ECG signal, blood pressure, oxygen saturation, and the principle of production, was theoretically analyzed. On this basis, the LED ECG monitoring circuit was designed. This circuit uses red and green LEDs as light emitting carriers. The sensor part and the signal conditioning circuit part have been designed in detail. Photovoltaic method (PPG) was used to improve the signal transmission capability. Further, the position of the circuit electrode and clothing was studied. Static state and dynamic state were set, and the experimental scheme of the corresponding electrode-garment binding position was designed. During the experiment, the ECG monitoring circuit was tested for performance based on ZEMAX simulation, including ECG monitoring capability and anti-jamming capability. In the electrode-clothing and position experiments, a large amount of position data was analyzed to select the most accurate and least binding position for monitoring. Finally, we conclude that the results show that the ECG monitoring circuit design was reasonable. It has better signal transmission capability and anti-jamming capability. In summary, the location of ECG monitoring and clothing binding is accurate, and it can well capture people's electrical activities.
