Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

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 ...

As the EV market grows, so does demand for robust magnetic field sensors within these vehicles. Stray magnetic fields may diminish the accuracy of these sensors, though, which is where active ...

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with ...

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes ...

The new magnetic sensor is inexpensive to make, works on minimal power and is 20 times more sensitive than many traditional sensors. A team of Brown University physicists has developed a new type of ...

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 ...
