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 ...

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 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 ...

If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...

Spintronics devices will be key to realizing faster and more energy-efficient computers. To give us a better understanding of how to make them, a Kobe University team now showed how different ...

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 ...

Most of the hacks we see around these parts have to do with taking existing components and cobbling them together in interesting new ways. It’s less often that we see existing components gutted and ...

The magnetic sense of migratory birds such as European robins is thought to be based on a specific light-sensitive protein in the eye. Researchers demonstrate that the protein cryptochrome 4, found in ...
