A Wearable Body Sensor Network for Personal Monitoring During Daily Life: Technology and Applications

This chapter introduces a wearable Body Sensor Network (BSN) that can monitor cardiorespiratory parameters, activity levels, and air quality. The system is composed of six units: three Inertial Measurement Units for respiratory monitoring and activity recognition, a pulse oximeter, a single-lead ECG, and an environmental monitor. The BSN is based on the ANT protocol, and there is a dedicated smartphone app to collect data from the different units. Previous research works with parts of the BSN are presented, including the development of a human activity recognition algorithm, an algorithm for respiratory signal extraction in dynamic conditions, and a validation of cardiorespiratory parameters monitoring in response to a physiological signal. In the conclusion, possible future developments are discussed, including studies on air quality measurements and exposure to pollutants, and the integration of other measurements into the BSN.
