Researchers built a fingernail-sized magnetometer using metasurfaces that measures fields billions of times weaker than Earth ...

A team led by physicists at Washington University in St. Louis has created quantum sensors that can survive in extreme conditions. Built inside unbreakable sheets of crystallized boron nitride, the ...

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with ...

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 ...

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 ...

As the EV market grows, so does demand for robust magnetic field sensors within these vehicles. Stray magnetic fields may diminish the accuracy of these sensors, though, which is where active ...

Over the past few decades, electronics engineers have developed increasingly sophisticated sensors that can reliably measure ...

Magnetic sensors detect moving ferrous metal. Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object ...

GRENOBLE, France--(BUSINESS WIRE)--Hprobe, a provider of semiconductor Automated Test Equipment (ATE) for magnetic devices, today announced the first industry turnkey testing equipment dedicated to 3D ...

Current sensing technologies and magnetic sensors have evolved remarkably to address the demand for accurate, real‐time monitoring in power distribution networks and industrial applications.
