TL;DR: This review explains the conventional BP measurement methods and their limitations; presents models to summarize the theory of the PTT-BP relationship; outlines the approach while pinpointing the key challenges; and discusses realistic expectations for the approach.

TL;DR: A smartphone-based device for cuff-less and calibration-free monitoring of systolic and diastolic blood pressure is comparable to cuff-based devices and extended the oscillometric principle, which is used by most automatic cuff devices, to develop a cuff-without BP monitoring device using a smartphone.

TL;DR: It is concluded that BCG is an adequate proximal timing reference in deriving PTT, and that BCg-based PTT may be superior to ECG-based PAT in estimating DP.

TL;DR: The results quantitatively indicate that PAT is not an adequate surrogate for PTT in terms of detecting challenging BP changes and is unable to meet the FDA BP error limits.

TL;DR: This work measured “scale PTT”, conventional PAT, and cuff BP in humans during interventions that increased BP but changed PEP and smooth muscle contraction differently, and assessed a bathroom weighing scale-like system for convenient measurement of ballistocardiography and foot PPG waveforms in terms of its ability to improve tracking of BP in individual subjects.
