Correlation of arterial blood pressure to synchronous piezo, impedance and photoplethysmographic signal features

Current Directions in Biomedical Engineering, 2017
In this paper we investigate which pulse wave pick-up technologies are well suited for blood pressure trend estimation. We use custom built hardware to acquire electrocardiographic, applanation-tonometric, photo- and impedance-plethysmographic signals ...
