Pulse oximeters, a type of photoplethysmography (PPG) sensor, are electronic devices that measure a person’s blood-oxygen saturation (SpO 2) and heart-rate (HR) levels. Since their inception in the ...

The use of HPGe detectors is chosen in situations where isotope identification is required due to their excellent resolution. In various circumstances, it is necessary to carry out these gamma-ray ...

Detecting a signal pulse is usually basic electronics, but you start to find more complications when you need to time the signal’s arrival in the picoseconds domain. These include the time-walk effect ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240009 , discusses a smart photonic wristband for pulse wave monitoring. Pulse waves are a prominent component of physiological ...
