Wearable device for measuring electrocardiogram and blood pressure pulse wave

Abstract

In this study, we report on a wearable device for measuring electrocardiogram (ECG) and blood pressure pulse wave simultaneously. The size of device is 125 mm × 85 mm × 75 mm, the mass of the main body and the battery are 130.6 g and 177.4 g, respectively. Our device consists of an ECG module for measuring ECG and triaxial force sensors for measuring blood pressure pulse wave. We could simultaneously measure the clear waveform of blood pressure pulse wave and ECG by our wearable device simultaneously. We extracted characteristic parameters from blood pressure pulse wave and ECG. It was compared each other. The correlation between the peak interval of the blood pressure pulse wave and the RR interval of the ECG was 0.91. We compared blood pressure pulse wave to ECG, and confirmed that the correlation between several parameters were high.
