Outline of Final Research Achievements

In order to confirm the possibility of cuffless blood pressure estimation using the wrist PPG, we worked on the development of an analysis method for PPG waveforms, the evaluation of the relationship between hemodynamics and PPG waveforms, and the development of a multivariate estimation method. We have developed a new method, which is different from the conventional method, to stably extract features from the PPG. The developed method can extract the features of the PPG stably, and is an effective method for daily health management.
