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 FAIRsharing record describes: The General Data Format for Biomedical Signals is a scientific and medical data file format. The aim of GDF is to combine and integrate the best features of all bio
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
Dehydration is a prevalent and serious problem among older adults. As people age, the body’s ability to conserve water decreases, and the sensation of thirst diminishes. This reduced sense of thirst m
