A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

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 ...

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 ...

A research team from the Institute of Space-Earth Environmental Research (ISEE) at Nagoya University in Japan used a sensor manufactured by Aichi Steel Corporation to build a magneto-impedance sensor ...

This file type includes high resolution graphics and schematics when applicable. The latest generation of 3D magnetic position sensors from ams AG uses a pair of sensor elements (pixels) that make it ...

Polymer thin-film optical cavities boost the magnetic sensing sensitivity of nanodiamond quantum sensors nearly fivefold ...

Imagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an ...
