The Art of Biosignals
Biosignal acquisition methods are still mostly bound to hospital and short-time data acquisition settings. Still, a paradigm shift is emerging, in which everyday technology is increasingly capable of measuring health data in a more pervasive manner. This is paving the way for systems that can better analyze and adapt to perceived changes in the health status or behavior of the user. In this talk we present an overview of biomedical data acquisition systems, with special emphasis on Electrocardiography (ECG), describe a novel approach that can be characterized as an evolution of wearable sensing, and provide a discussion of the main challenges posed by these new methodologies. The work is targeted at pervasive biomedical sensing through signal acquisition at the hand palms or fingers, by providing simplified sensor setups that can be integrated into virtually any object with which the person interacts with. Experimental results show that data acquired using our proposed approach is highly correlated with data obtained through conventional methods.
