Abstract
Wearable remote health monitoring systems have gained significant prominence in the recent years due to their growth in technological advances. One form of the Wearable Physiological Monitoring System (WPMS) is the Wearable Body Area Networks (WBAN) used to monitor the health status of the wearer for long durations. The paper discusses a prototype WBAN based wearable physiological monitoring system to monitor physiological parameters such as Electrocardiogram (ECG) and Electroencephalogram (EEG) acquired using a textile electrode, Photoplethysmogram (PPG), Galvanic Skin Response (GSR), Blood Pressure derived from analysis of Pulse Transmit Time (PTT) and body temperature. The WBAN consists of three sensor nodes that are placed strategically to acquire the physiological signals and the sensor nodes communicate to a chest/wrist worn sink node also known as wearable data acquisition hardware. The sink node receives physiological data from the sensor nodes and is transmitted to a remote monitoring station. The remote monitoring station receives the raw data and it is processed to remove noises, such as power line interference, baseline wander and tremor in the signals and the information is extracted and displayed. The WBANs are designed using the ZigBee wireless communication modules to transmit and receive the data. At the remote monitoring station the physiological parameters such as heart rate, pulse rate, systolic, diastolic blood pressure, GSR and body temperature are continuously monitored from the wearer. The data acquired from the wearable monitoring system is statically validated using a qualified medical device on 34 subjects.
Highlights
The proposed wireless wearable physiological monitoring system consists of three sensors nodes placed strategically at specific locations on the human body to acquire the physiological parameters
The sensor node 3 is to acquire PPG and Galvanic Skin Response (GSR) signals, the PPG signals are picked from the index finger and the GSR is picked from the medial positions of the index finger and middle finger
The Wearable Body Area Network (WBAN) consists of three sensor nodes, wearable data acquisition hardware and remote monitoring station
Summary
The reasons for occurrence of these diseases are stress, change in life style, bad food habits, smoking, alcohol consumption, lack of exercise, etc. Proper management of health is vital for maintaining a healthy lifestyle, which requires visit to hospital and a regular health checkup, which was lacking. There is a need to monitor the health status of the individuals non-invasively and at early stage of the disease. Non-invasive devices are commonly available in the market for measurement of various physiological parameters for use in hospitals, clinics and at home. There is a need for monitoring the health status of the individuals while they perform their routine activities, which is possible by use of wearable devices known as Wearable Physiological Monitoring System (WPMS)
