The Cuffless Blood Pressure Measurement with Ballistocardiogram and Photoplethysmogram

In order to decrease the infection of COVID-19 virus, people must frequency wash the hands or decrease the times of touching the public things. The blood pressure (BP) and weight are the important parameters under the healthy management. The goal of this study is to measure BP with a weight scale. The Ballistocardiogram and photoplethysmogram (PPG) were measured to extract the pulse transit time (PTT) that was used to estimate BP. The results show that the performances of proposed method were close to the reference method, using the electrocardiogram and PPG. Thus, the proposed method can decrease the infected risk when measuring BP with the cuff.
