The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Low-dimensional magnetic heterostructures are a key element of spintronics, where magnetic interactions between different materials often define the functionality of devices. Although some interlayer ...

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 ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft ...

Researcher Michael Romalis from Princeton University tests out the in-the-field MEG recording apparatus. (Courtesy: Mark Limes) A portable sensor that can detect tiny biomagnetic signals from the ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use of spin defects in hexagonal boron nitride (hBN) as powerful, ...
