Electrons move inside graphene almost without any hindrance from the atoms of the two-dimensional carbon sheet. This good transport property is of interest to the development of magnetic field sensors ...

MIT engineers have developed a magnetic transistor that could pave the way for smaller, faster, and more efficient electronics. By replacing silicon with a magnetic semiconductor, the team created a ...

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 ...

A new device concept opens the door to compact, high-performance transistors with built-in memory. (Nanowerk News) Transistors, the building blocks of modern electronics, are typically made of silicon ...

Researchers at the Korea Institute of Science and Technology (KIST) in Seoul have created a transistor that is switched by magnetism, rather than electricity. This could lead to computer chips that ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

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 ...

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 ...
