A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is ...

Apple has filed for a patent (number US 20240247929 A1) for an “Electronic Device With Optical Angle Sensor” that hints at foldable iPhones, iPads, and even Macs. A July 23 DigiTimes report says Apple ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...
