Magnetic Field Sensor

A Magnetic Field Sensor is pretty much exactly what it sounds like. They detect the magnetic fields emitted by magnets of either a temporary or permanent nature, and allow extrapolation of where the magnetic poles are.


With regards to VR they may be used for some varieties of motion capture, where the markers used to track the positions of the limbs are magnetic rather than optical in nature.

With regards to AR, a magnetic field sensor is considerably more essential. They are used in small groups to create tiny solid state compasses which can be integrated onto a microchip in order to track the direction the user is facing by triangulating the position relative to the planet's magnetic north pole from the data received by each sensor.

Without this data it would be very difficult to precisely track the direction the user is facing, and there would be major issues in perfectly aligning the virtual and physical visual data on top of one another.

Magnetic Resonance Sensor in a Sugar Cube of Space
The debut of a new type of magnetic resonance sensor for brainwaves and electrical activity - which changes the game totally for both fMRI and MEG. For the first time ever, portable, low-cost versions of both are actually a possibility.

Pieces of the Sensor Web > AMPERE
AMPERE is one of the many dedicated networks necessary to protect and grow a fledgeling sensor web. Looking down from space, 66 satellites monitor the Earth's electromagnetic field - and watch for spikes.

RFID: Beginnings of the sensor web?
RFID ? Radio Frequency Identification. These small tags are starting to drift everywhere. Powered by the radio field the reader sends out when it scans for a tag, these tiny, primitive devices may actually be heralds of the sensor web.

A Sensor Web Built from Every Screw?
Imagine a world where every bolt that holds together the frame of the building you are in, holds together the car you drive, the planes in the air, and heavy machinery all around, is also a sensor. A vibration sensor, torque sensor, continually reporting on the stresses and strains on the structure in real-time. This is what German engineers have been working on for a number of years, and such screws and bolts are what they have now succeeded in making.

Extra Sensory Perceptions: Sensing Magnetic Fields
The first known, successful implant of an extra sensory perception to detect magnetic fields the person with the new sense was near, occurred in 2005, when a small piece of neodymium, which is a rare earth metal, that forms a permanent magnet, was coated in a thin layer of silicon, and implanted into an emergency medical technician's finger.

Sensor Webs Monitoring Microclimates
How do you set up a sensor web in a forest? Solar power is useless thanks to the canopy. Wildlife will get tangled up in the cables, as will people trying to manage the forest. Units need to be monitored for damage requiring dedicated staff on-site. If only we could fix all these problems, we could use sensor webs in remote areas... What's that? They're all fixed, you say?

Wireless Sensor Detects Status of Window
German researchers have made advances in the sensor systems that detect if a window is open or closed, by using of all things, a heavily modified washing machine tumble sensor. It detects movement ofthe window flawlessly, by the exact same means.

An Air Quality Sensor Web Made From iPhones
Researchers at the University of California demonstrate how to turn thousands of private iPhones into a single real-time sensor web, with the help of a plug-in sensor, and an app that provides enough real immediate benefit to the iPhone users thatthey'll run it much of the time. In this case, air quality sensors, complementing (and exceeding) the capabilities of the traditional air quality weather stations.

Chemical Sensor as Sensitive as a Dog's Nose
A technological scent sensor that works in almost the exact same manner as a bog's biological nose has been developed by researchers at the University of California. The sensor, the size of an adult male fingerprint, uses microfluidic nanotechnology to mimic the biological mechanism behind canine scent receptors. The device is both highly sensitive to trace amounts of certain vapour molecules, and able to tell a specific substance apart from similar molecules.

HyGreen - Intelligent Hygiene Sensor web
A novel take on the sensor web has been unveiled by US firm Xhale incorporated, consists of a wireless network of soap dispensers, which contain sensors capable of detecting whether the hand waved under it, has recently been sanitized or not.
