There are many types of magnetic field sensors on the market. A brief list would include (but not be limited to) these, with the more exotic devices first: The MEMS solutions are gaining market share ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

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 ...

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 ...

Application characteristics help specifiers choose the best discrete sensor type. Industrial automation systems depend on sensors to detect what is going on with machinery and products for effective ...

The Apple iPhone brought the benefits of integrated multi-sensor technology to the masses, and while the application of sensors and their associated algorithms has multiplied and changed the world ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

In the laboratory: Taner Esat from Forschungszentrum Jülich. (Courtesy: Forschungszentrum Jülich / Sascha Kreklau) Researchers in Germany and Korea have fabricated a quantum sensor that can detect the ...

The low power consumption, cost-effectiveness, and smaller footprints offered by Hall-effect sensors make them strong candidates for a wide range of designs and applications. The main trends in ...
