Part 2 covers the pulse based counting method and the various sensors that are used in industry and the way they generate different pulse waveforms to be used in variety of flow meters. This part will ...

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.

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.

The Wii Vitality Sensor was announced in 2009 but has never seen the light of day — and Professor Roger Quy thinks he knows why. Speaking at the recent NeuroGaming Conference in San Francisco, Quy ...

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 ...
