Melexis unveils the MLX90296, a new micropower linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is ...

Researchers have developed a precision magnetometer based on a special material that changes optical properties in response ...

In labs around the world, scientists chase forces too faint to see and too small to touch. They hunt for tiny magnetic signals that ripple across materials atom by atom. Those signals hold clues to ...

Genetic analysis of inner ear tissue revealed cells with highly sensitive electric sensors, the same ones used by sharks to detect their prey. "The cells we describe are ideally equipped to detect ...

Quantum devices that measure Earth's magnetic fields could help replace GPS—if researchers can figure out how to tell when such devices are working well, or even at all. A Pentagon contract suggests ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

Two new omnipolar sensors employ tunneling magnetoresistance (TMR) technology to offer an alternative to Hall-effect devices by providing superior thermal stability, wide supply voltage compatibility, ...

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 ...

Imagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an ...
