Wearable biosensing: signal processing and communication architectures issues

Long-term monitoring of human vital signs is becoming one of the most important fields of research of biomedical engineering. In order to achieve weeks to months of monitoring, new strategies for sensing, conditioning, processing and communication have to be developed. Several strategies are emerging and show different possible architectures. This paper essentially focuses on issues in wearable biosignal processing and communication architecture currently running at the Swiss Center for Electronics and Microtechnology (CSEM) in the framework of several European projects. Keywords— wearable sensors, wireless BAN, biosignal process-
