Abstract
The present invention relates to a method and system for estimating blood pressure of a subject. In particular, but not exclusively, the method involves receiving a photoplethysmogram (PPG) signal from a light-based Pulse-Plethysmography sensor applied to the skin of a subject and reconstructing a pulse blood pressure waveform between systolic and diastolic blood pressure of the subject. Additionally, but not exclusively, the method involves processing the pulse blood pressure waveform and reconstructing an absolute blood pressure waveform of the subject.
