Understanding diffraction and dispersion is key to optical science, influencing technologies like spectroscopy, fiber optics, ...

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman spectroscopy and ...

Apple has unveiled a world-first feature that can alert users to deadly high blood pressure – and the company claims it could flag more than one million undiagnosed cases in its first year alone. The ...

Imagine a touch sensor so thin and flexible it can feel not only where you press but also how hard. Scientists in Japan have ...

Of course, these aren’t the only great gaming mice – products have matured over the years so features like sensor accuracy, responsiveness, and durability are better than ever, and anything worth its ...

A few weeks back, we reported on a research group that figured out how to measure heartrate using perturbations in WiFi signals. [Nick Bild] was interested in this so-called “Pulse-Fi” technique, but ...

The optical system is central to a star sensor, focusing starlight onto the image sensor. The tracker's reliability and ...

When it comes to exercising, your heart rate is the gold-standard metric to uncover how hard you're pushing. It tells you whether you're working aerobically or anaerobically, how your body is reacting ...

The G502 X isn't a whole lot different to the older G502 gaming mice, but manages to bring some useful ergonomic and weight tweaks to an already stellar design, in order to make it appeal more to FPS ...
