A wearable vital signs monitoring system for pervasive healthcare

Remote monitoring of vital signs is an important technique to ensure the health and life quality of a patient. A wearable monitoring system for low-cost and pervasive healthcare is proposed in this paper. The system, which comprises of wireless module, miniaturized electrocardiogram (ECG) sensor and photoplethysmogram (PPG), is able to measure and analyze physiological signs in real-time and with minimum disturbance on daily life. With Bluetooth communications, a phone is able to exchange data with the sensors deployed on body and display the ECG/PPG waveforms as well as the significant physiological variables including heart beat rate, oxygen saturation (SpO
₂
) and systolic blood pressure. The wearability of the system provides great convenience and continuous healthcare service to the user.
