Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor has no moving ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

[Joel] dug up this hack that he pulled off over ten years ago. It’s inspired by the Nintendo PowerGlove, and uses flex sensors to react to movements of your fingers. The interesting thing is, he built ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Maxim Integrated introduces it’s new MAXREFDES27# IO-Link subsystem reference design that lets operators tune and calibrate an optical proximity sensor with excellent accuracy, up to 14 bit resolution ...
