Wearable Ballistocardiography system for heartbeat detection

Ballistocardiography (BCG) is a non-invasive method based on the measurement of the human body motion occurring due to acceleration of blood as it is ejected and moved in the large vessels at each cardiac cycle. The system presented in this paper is designed to measure the reaction force of systolic contraction of the body after determining the pumping of blood into the aorta and pulmonary artery and also the reflected signals in the form of signal correlated with ECG signal. The system is embedded into a cushion and clothing, giving the advantage to automatically perform investigations of physiological parameters using ballistocardiograph method and the accelerometer sensor.
