Unobtrusive heart rate estimation during physical exercise using photoplethysmographic and acceleration data

Abstract: Photoplethysmography (PPG) is a non-invasive, inexpensive and unobtrusive method to achieve heart rate monitoring during physical exercises. Motion artifacts during exercise challenge the heart rate estimation from wrist-type PPG signals. This paper presents a methodology to overcome these limitation by incorporating acceleration information. The proposed algorithm consisted of four stages: (1) A wavelet based denoising, (2) an acceleration based denoising, (3) a frequency based approach to estimate the heart … Show more

“…Very recently, a number of signal processing techniques have been proposed for separating true PPG components from motion artifact components in order to allow PPG-based heart monitoring during physical exercise for the first time. See [3,[5][6][7][8][9][10][11][12] as a small number of example algorithms. with no motion present shows clear peaks for each heart beat, here for a participant with a low resting heart rate of 42 beats per minute.…”

“…This was observed to facilitate convergence of the adaptive filters and improved the estimation accuracy, by achieving an AAE of 1.25 BPM. Investigating the same problem [19]- [21] achieved AAE of 1.8, 1.77, and 1.96 BPM respectively.…”
