This paper proposes a novel unconstrained monitoring system that measures heart and respiratory rates and evaluates autonomic nervous activity based on heart rate variability. The proposed system measures the aortic pulse waves (APWs) of a patient vi

This paper proposes a novel technique to estimate continuous pulse pressure waves based on aortic pulse waves (APWs) that are measured in an unconstrained manner at the back of a user via an APW sensor. Frequency filtering and rectification are appli

This paper proposes a system to extract biological signals from aortic pulse waves which are measured by a microphone type pulse wave sensor. Theproposed system enables extraction of three biological signals corresponding to respiratory rate, pulse p
