Imagine navigating virtual reality with contact lenses or using your smartphone underwater: These and other possibilities may ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

Instead of using just one magnetic sensor, [Peter] is building a two-dimensional array of magnetic sensors. Basically, it’s just a 12×12 grid of Hall effect sensors wired up to a bunch of ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Published in Green Energy and Intelligent Transportation, the study explores how magnetic sensors can analyze battery-specific magnetic fields, laying the foundation for a more secure and ...

Scientists in Spain have created tiny flower-shaped structures that can boost magnetic fields in a very small area. These ...

1a,b) that now contain ferromagnetic nickel because it is cheap. We show that MLCs therefore inadvertently function as room-temperature (RT) magnetic field sensors that require no electrical power.

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
