Non-contact Cardiac Health Monitoring System Based on Combined ECG-SCG Measurement

Abstract

Cardiovascular disease is a leading cause of death in society, so the prevention and treatment of this disease has gradually received more attention. This paper proposes a non-contact cardiac health monitoring system based on combined ECG-SCG measurement. The monitoring system can realize the synchronous measurement of ECG and SCG signals, so as to obtain more abundant cardiac physiological information, which helps to improve the specificity and accuracy of the diagnosis of cardiac disease. The ECG measurement of the monitoring system is based on capacitive coupling electrodes, and the SCG measurement is based on a three-axis MEMS accelerometer. The non-contact measurement method can improve the comfort of patients during the cardiac health monitoring process, and is beneficial to realize long-term monitoring of cardiac health. It has been verified that the monitoring system can achieve high-quality signal measurement, and can collect ECG and SCG signals under different clothing thicknesses and various motion states.
