The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various ...

Recent studies have shown metallic objects have their own magnetic fingerprints based on size, shape and physical composition. Scientists look to leverage these observations to potentially create a ...

One of the primary ways that gyroscopic motion can be applied is in the monitoring and/or maintaining of the orientation of an object. A broad array of engineering applications are based on gyroscopic ...

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 ...

Tiny deviations: the new metal detector looks for minute disturbances in Earth’s magnetic field. (Courtesy: iStock/muffinmaker) A compact, low-cost and low-power metal detector that can identify the ...

Impact of stray magnetic fields on the electrification of motor vehicles. The role of inductive sensors to reduce risk, cost, and size in EMI-laden applications. The clean and efficient design of ...

Measuring magnetic fields with accuracy is important, whether it’s for geological exploration or medical imaging. Now, a team from MIT has developed a new laser-based magnetic field detector that’s ...
