CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...

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 ...

Measurement systems that are able to accommodate evolving application requirements are preferred as growing cost pressures demand long system life and functional flexibility. The most efficient way to ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

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.

Optical sensors may be uniquely suited for use in robotic hands, according to Carnegie Mellon University researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber ...

Optimizing office environments Infrared sensors that measure mean radiant temperature better reflect the heat levels that individuals perceive. (Courtesy: iStock/AntonioGuillem) The internal ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...
