In personal healthcare, blood pressure (BP) is an important vital sign to be monitored frequently.However, traditional BP measurement devices require cuff's inflation and deflation that very uncomfortable for many users.Cuffless noninvasive estimation methods are attractive especially on using Photoplethysmography (PPG) approach achieving continuous monitoring minimal user's inconvenience.From recent studies the second derivative of PPG (SDPPG) vascular aging, SDPPG contains information about aortic compliance stiffness, which highly related pressure.To making use this new finding, 14 based features proposed in paper.They combined with conventional 21 time-scale develop a Support Vector Regression estimator.Experimental results demonstrated estimator could improve accuracy by 40%.Index Terms-Blood pressure, photoplethysmography (
