Emerging Silicon-Based Magnetic Sensors Which Include Anisotropic Magnetoresistive (AMR) and Giant-Magnetoresistive (GMR) Sensors Are Finding New Applications and Challenging the Conventional Hall Sensors.


DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c49941) announces the addition of Frost & Sullivan's new report Magnetic Sensors-Emerging Technology Developments to their offering.

This Frost & Sullivan research service titled Magnetic Sensors-Emerging Technology provides analyses of hall sensors, fluxgate A detector which gives an electrical signal proportional to the intensity of the external magnetic field acting along its axis. Also called fluxvalve. , search coil A search coil is a device for measuring eye movements. It uses coils that are embedded into a tightly-fitting contact lens or a rubber ring that adheres to the eye. An alternating magnetic field with horizontal and vertical components is used to induce electric currents in these , anisotropic/giant/colossal magnetoresistance A change in electrical resistance in metal or a semiconductor when it is subjected to a magnetic field. The property of magnetoresistance is used in reading the bits on magnetic tape and disk.  sensors, giant magetoimpedance, and SQUID among others, along with key drivers, challenges, restraints, analysis and forecasts of technologies that shape the future semiconductor testing industry.

In addition, ultra-large magnetoresistance are observed in new materials which is far more superior to the GMR effect. Every year, over three hundred million hard disks are manufactured all over the world. In every hard disk, lies a magnetic read head that is likely to be using the GMR sensing technology. The significant growth of about 60 percent in hard disk area density each year is bolstered by GMR technology. To sustain growth in the near future, companies are likely to be investing in GMR technologies to support higher area density for hard disks.

 and Development of Killer Applications Killer Application

Killer application or "killer app" is a buzzword that describes a software application that surpasses all of its competitors.

Notes:
The term is sometimes used to describe a type of software.
 Expected to Boost Advancements in this Space

In the current business scenario, miniaturization plays an important role in technological advancement. Micro-electro-mechanical-systems (MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. ) and silicon processing provide the platforms for miniaturizing sensor dimensions and integration with mechanical and electronic features. Sensors based on MEMS technologies and smart sensors are the focus of the current sensor A current sensor is a device that detect electrical current (AC or DC) in a wire, and generates a signal proportional to it.

The sensed current and the output signal can be:

"'Killer applications' such as these are likely to boost the development of such magnetic sensors."
