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 ...

Magnetic sensors quietly underpin everything from smartphone compasses to the stability systems that keep electric vehicles on the road, and the race to make them smaller, faster and more sensitive is ...

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 used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...

In the laboratory: Taner Esat from Forschungszentrum Jülich. (Courtesy: Forschungszentrum Jülich / Sascha Kreklau) Researchers in Germany and Korea have fabricated a quantum sensor that can detect the ...

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 ...
