Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers ...

Illustration shows how a smartphone magnetometer can measure a host of biomedical properties in liquid samples using a magnetized hydrogel. Nearly every modern cellphone has a built-in compass, or ...

The magnetometer in your smartphone helps you navigate by powering the device's digital compass. Now researchers have found a way to use it to navigate body chemistry by reading your glucose levels, ...

We just got a couple images from one of our Apple ninjas and it appears to show a compass option in one of the debugging menus. Our source says this is obviously for a built-in magnetometer in the ...

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers ...

Researchers from the National Institute of Standards and Technology (NIST), Boulder, Colorado, say a smartphone compass could be used to analyze biomarkers in body fluids — blood, sweat, urine, or ...

For smartphones, tablets and other handheld devices, the MXG1300 is a magnetometer-based, e-Compass sensor, built using the company's own low-noise, 0.18-µm technology. Featuring an Android OS driver, ...

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 ...
