Does a miniaturized ring sensor accurately detect beat-to-beat pulsation compared to FDA-approved PPG and ECG?
A novel, power-efficient, artifact-resistant PPG ring sensor demonstrates comparable performance to FDA-approved devices for continuous beat-to-beat monitoring.
Rhee et al. (2001) studied this question. Ring sensor (photoplethysmograph) vs. FDA-approved PPG and electrocardiogram was evaluated on Detection of beat-to-beat pulsation. A prototype finger-ring photoplethysmograph sensor was comparable to FDA-approved PPG and electrocardiogram devices in detecting beat-to-beat pulsation despite motion artifacts and disturbances.
