A Body Sensor Network integrating miniaturized ECG, PPG, and PCG sensors with tri-axis accelerometers and IEEE 802.15.4 synchronization was developed for continuous vital sign monitoring.
Presents a synchronized wireless body sensor network for continuous, motion-tolerant monitoring of multiple cardiovascular vital signs.
Prophylaxis and rehabilitation of cardiovascular disease require the development of biosignal acquisition and processing devices that are capable of supporting patients in their everyday life. This paper presents a Body Sensor Network (BSN) for use in Personal Healthcare applications. It consists of miniaturized sensor modules for electrocardiogram (ECG), photoplethysmogram (PPG) and phonocardiography (PCG) which are wirelessly connected with a coordinator to collect the data. Each sensor module is combined with a tri-axis accelerometer for patient's posture and activity measurement. As it is possible to extract further information about the health state by fusioning data of different biosensors, the wireless link based on IEEE 802.15.4 was extended by a synchronisation mechanism enabling synchronous sampling of the individual sensors. An adaptive application of algorithms for signal pre-processing and analysis allows the reduction of the transferred data.
Volmer et al. (Fri,) conducted a other in cardiovascular disease. Body Sensor Network (BSN) was evaluated. A Body Sensor Network integrating miniaturized ECG, PPG, and PCG sensors with tri-axis accelerometers and IEEE 802.15.4 synchronization was developed for continuous vital sign monitoring.
