WashU physicists build quantum sensors in boron nitride sheets to study magnetism and stress under extreme pressure.

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 ...

As a result of the tetrahedral symmetry of the lattice, a diamond crystal typically contains NV centers in four orientations.

Researchers from Japan have discovered a unique Hall effect resulting from deflection of electrons due to "in-plane ...

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 ...

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 ...

Magnetoresistance (MR), the change in the electrical resistance of a material due to the influence of an external magnetic field, has been widely used in magnetic sensors, magnetic memories, and hard ...

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 ...

Most of the hacks we see around these parts have to do with taking existing components and cobbling them together in interesting new ways. It’s less often that we see existing components gutted and ...

A cadence sensor is a compact cycling device that measures pedaling rate in RPMs to provide real-time feedback.
