A four-channel ink-writing photoplethysmograph FP-4
TL;DR: The FP-4 enables arteries, arterioles, or veins of any caliber to be investigated, and the circulation time may be measured, and a special calibrated device enables a quantitative analysis of vascular reactions to be made.
Noncontact measurement of heart rate using facial video illuminated under natural light and signal weighted analysis
TL;DR: In this article, the authors presented a novel optical imaging-based method to measure the vital physical signals, using a digital camera and ambient light, the cardiovascular pulse waves were extracted better from human color facial videos correctly.

Pulse Wave Generation Method for PPG by Using Display
TL;DR: In this paper , a method that enables a photoplethysmography (PPG) sensor to measure arbitrary pulse data by using a display was proposed, and the results showed that the error between the target heart rate and the heart rate acquired by the smartwatch was within 3 beats per minute (bpm).
Journal ArticleDOI
Delineation and Analysis of Seismocardiographic Systole and Diastole Profiles
TL;DR: This research work proposes a delineation framework to identify various systole and diastole fiducial points with the help of a photoplethysmogram (PPG) signal and an envelope construction scheme is proposed to estimate the prominent peaks of the PPG signal.
