This paper presents the design, implementation and test of a watch with the capability to measure multiple physiological signals, such as photoplethysmography (PPG), electrocardiography (ECG), and some physiological parameters extracted from PPG and ECG. Based on the PPG and ECG signals, the pulse rate and heart rate could be extracted respectively. Moreover, the pulse transmit time (PTT) could be...
A multifunction wearable noninvasive ambulatory monitoring sensor based on Electrocardiogram (ECG) and Impedance Cardiography (ICG) has been designed, fabricated and tested. The electric function (with ECG) and mechanical function (with ICG) of the heart can be monitored simultaneously and continuously. Based the RR serials computed from ECG waveform, the sympathetic and parasympathetic function of...
