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 ...
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 ...
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 ...
This technical article describes monolithic magnetic sensor integrated circuits (ICs), its operation, and explains how it uses a technique called dynamic quadrature offset cancellation. The offset ...
If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...
(Nanowerk News) In a scientific breakthrough, an international research team from Germany's Forschungszentrum Jülich and Korea's IBS Center for Quantum Nanoscience (QNS) developed a quantum sensor ...
A guide for engineers balancing performance, reliability, and manufacturability across today’s smart systems By Barry Brents, ...
Researcher Michael Romalis from Princeton University tests out the in-the-field MEG recording apparatus. (Courtesy: Mark Limes) A portable sensor that can detect tiny biomagnetic signals from the ...
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 ...
