To solve this problem, a team led by Penn State researchers looked first not to the future, but back—to principles of pulse monitoring in traditional Chinese medicine, first described more than ...

Inside this sensor is an infrared LED and a phototransistor. Of course with a finger over the sensor there is a ton of noise both from ambient light and the base rate of reflected light from a ...

Sensor enables high-fidelity input from everyday objects, human body A new technique for recording and analyzing surface-acoustic waves can enable nearly any object to act as a touch input device ...

Parts designed and marketed for a specific application can nevertheless still be useful in other ways, and whenever that happens, it’s probably the start of a pretty good hack. Using a sensor… ...

Google has received FDA clearance for the Pixel Watch 3's Loss of Pulse Detection feature and it will roll out to US users next month.

At their core, sensors convert real-world stimuli—temperature, motion, pressure, light, proximity, and more—into measurable ...

Pulse-ranging-technology sensors emit short bursts of high-intensity laser light at up to 250,000…times/sec. The light intensity of a PRT sensor can be up to 1,000× greater than that of a phase ...

Tunable resistive pulse sensing (TRPS) is a method used to provide quantitive size measurements in single particle analysis.

Masimo SET measures oxygen saturation (SpO2), pulse rate (PR), perfusion index (PI), and PVI, a measure of the dynamic changes in PI that occur during the respiratory cycle.
