Measurement of respiratory rate using wearable devices and applications to COVID-19 detection
npj Digital Medicine, 2021 We show that heart rate enabled wearable devices can be used to measure respiratory rate. Respiration modulates the heart rate creating excess power in the heart rate variability at a frequency equal to the respiratory rate, a phenomenon known as ...
