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 ...

Nanodiamond quantum sensors mounted on magnetic microbots achieve coherent spin control while moving freely through fluid, a ...

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.

Quantum mechanics states that electrons have two stable spins—up and down. With the advent of nanoscale fabrication methods, device companies are harnessing this knowledge to create devices. The ...

In an interview with pv magazine, cybersecurity expert Mohammad Al Faruque explains how seemingly simple sensors in PV systems and other energy systems are surprisingly vulnerable to magnetic, ...

As with actors and opera singers, when measuring magnetic fields it helps to have range. Researchers led by Katja Nowack, assistant professor of physics, created this micron-scale Hall-effect sensor ...

The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic ...

A new family of permanent magnet linear displacement (PLCD) sensors is based on the electromagnetic induction principle, which places a primary winding around a soft ...

It will be fascinating to see which GPS alternatives, if any, take a dominant role in non-GPS settings, or will it be a ...

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 ...
