We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

This paper introduces Hall-effect technology and then explores how it has been applied, in particular, differentiating between the primary types of Hall sensor ICs, and the highly differentiated range ...

An advance in the use of antiferromagnetic materials in memory storage devices has been made by an international team of physicists. An advance in the use of antiferromagnetic materials in memory ...

Scientists at Ames National Laboratory, in collaboration with Indranil Das's group at the Saha Institute of Nuclear Physics ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

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

As iPhone gamepads go, the Backbone Pro sits right at the top end. It costs a whopping $169.99/£159.99, more than three times ...
