In our study, we utilized the MESA and Apple Watch datasets as validation datasets to assess the generalizability of proposed methdology. These datasets were chosen for their broad demographic coverag
Photoplethysmography (PPG) based consumer wearable devices have been widely used for continuous health monitoring. However, PPG is vulnerable to the contact pressure (CP) between sensors and human ski
This shows how the PPGs are analysed to calculate the signal-to-noise ratios of the two photoplethysmography systems. Note that the original raw analogue filtered signal (0.3−30 Hz) is further digital
