Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on ...

A new method using a combination of strong and weak electric fields to change nanoparticle speed and direction could improve ...

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...

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 ...

The idea of electric field was introduced by Michael Faraday. The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses. The ...

Scientists have developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices. TU Wien has developed a sensor ...
