This part will take a deep dive on the methods to perform the measurement of these pulses. Pulse Sampling Theory Sensors based on Pulse Counting Theory (discussed in Part 2 of the series) convert the ...

Pulse oximetry is a non-invasive means for measuring blood oxygen saturation and pulse rate, with typical sensors based on rigid electronics. Here, the authors develop a pulse oximeter based ...

These photoplethysmographic sensors operate by shining light into someone’s flesh – usually a finger or ear lobe – and recording the light reflected back to the source.

These variations make it difficult for current wearable pulse sensors to accurately record useful data, which is especially problematic for those with cardiovascular disease or high-risk factors ...

Larger and more sophisticated sensors would give details of the pulse – its duration and intensity – indicating what equipment might have been damaged and how badly.
