Figure 1: Principles of the magnetic sensor, which is based on individual nitrogen-vacancy electronic spins in diamond. The ideal preparation, manipulation and detection of an electronic spin would ...

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

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Quantum physics: The human body is controlled by electrical impulses in, for example, the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could ...

Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

RVmagnetics' MicroWire technology offers the smallest passive sensor, facilitating deep, internal sensing for advanced ...

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.

Next generation electronic devices face major technical challenges, which will affect both power management performance and efficiency. Increasingly, conversion and power management applications are ...
