University of Chicago scientists have discovered how to make magnetic sensors capable of operating at the high temperatures that ceramic engines in cars and aircraft of the future will require for ...

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings ...

We’re probably all familiar with the Hall Effect, at least to the extent that it can be used to make solid-state sensors for magnetic fields. It’s a cool bit of applied physics, but there are other ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

This article provides an in-depth overview of the significance and recent advancements of graphene in Hall effect sensor application. How Do Hall Effect Sensors Work? Hall effect sensors are ...

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. Researchers have developed a light-based technique ...

Researchers demonstrated a magnet-based system that can track the location of muscles and could be used to help people control prosthetic limbs and other wearable robotic devices. Using a simple set ...

Researchers have come up with a tiny, wire-free capsule that can be swallowed to print living materials directly inside the ...

This energy management interface is the "brain" of a self-powered, battery-free sensor that can harvest the energy it needs to operate from the magnetic field generated in the open air around a wire.
