Avago Technologies announced the availability of a new family of optically-isolated voltage sensors. This family is the industry’s first series of optical isolation amplifiers based on sigma-delta ...

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 ...

Researchers are making key advances with a new type of optical sensor that more closely mimics the human eye's ability to perceive changes in its visual field. Researchers at Oregon State University ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

(Nanowerk Spotlight) The term membrane potential refers to the electrical potential difference between the inside of a cell and its surrounding extracellular fluid. This phenomenon is present in all ...

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 ...

Readers with long memories will remember the days when mice and other similar pointing devices relied upon a hard rubber ball in contact with your desk or other surface, that transmitted any motion to ...
