While TMR works differently, it's a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet ...

A new study examined the mechanism governing the nonlinear Hall effect, paving the way for battery-free devices.

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...

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 ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

The A139x family, released by Allegro since 2005, is a Hall-effect sensor IC family that has only 10 mW power consumption in the active mode with tri-state output and user-selectable sleep mode. A ...

A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster and ...

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 ...

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 ...
