Magnetic Sensors-Emerging Technology Developments
This Frost & Sullivan research service titled Magnetic Sensors-Emerging Technology provides analyses of hall sensors, fluxgate, search coil, anisotropic/giant/colossal magnetoresistance 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.
This analysis is available through our Technical Insights Growth Partnership Service program. With this program, clients receive industry-leading market research such as this, along with technical and econometric data as well as many interactive features including Analyst Inquiry Time and Client Councils.
The following technologies are covered in this research:
Widespread Adoption in a Multitude of Applications Combined with Growth of Hard Disk Area Density to Boost Technology Developments
Magnetic sensors have come a long way from purely serving navigation purposes in ancient times. The technology for sensing magnetic fields has evolved due to the ever-increasing need for improved sensitivity, smaller form factor, and compatibility with electronic systems. "In the medical industry, ultra-sensitive superconducting quantum interference devices (SQUID) are finding a niche, and many new applications are proposed for high temperature SQUID systems," according to the analyst of the study. "These applications provide detection capabilities beyond existing technologies and serving applications such as airport security and structural stability among others."
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. 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.
Miniaturization and Development of Killer Applications 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) 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 development. MEMS technology not only shrink device dimension, but also integrate the sensors with electronics and mechanical components in a minimal space.
In addition, sensors built on silicon wafers are ubiquitous in the industry and have been successful in providing more electronic and signal processing features to the sensors, thus increasing production and lowering costs. "In addition to their use in compassing applications, AMR sensors have potential to make inroads against hall effect sensors in high-volume (for example, automotive or other) applications, particularly if their prices decline," explains the analyst. "‘Killer applications’ such as these are likely to boost the development of such magnetic sensors."

Open Call of Sensors Development for Mesh Network
Telepathx Ltd the Melbourne Australia based wireless communications developer is inviting academics and sensor developer’s world wide to partake in its proposed state wide 150 million dollar RFID mesh network, the first of many such networks being proposed by the company. This is an open call to developers to be part of the latest trend in wireless sensing technology ‘RFID mesh networks’ designed to enhance the quality of life in urban and rural communities.
The Telepathx Urban RFID mesh network is an autonomous sensor network that will monitor an estimated 100,000 kilometres of road, power line and essential services networks for faults events and hazardous conditions.
Our concept is simple; we build and operate wireless sensor networks capable of monitoring and identifying any asset, apparatus, event or condition within 100 meters of a power line or roadway that utilises our networks and proprietary RFID coding.
Energy Distribution Networks
Our goal is to enhance the development of intelligent self managing energy distribution networks and foster development of next generation switchgear technology that will power communities safely into the future. Particular interest is in fault identification and condition based monitoring of overhead and underground assets.
Intelligent Transport Systems (ITS)
The Telepathx RFID urban mesh network will allow for the monitoring, advising and controlling of roadside transport infrastructure. The innovation of using low cost RFID as the edge component, coupled with the Telepathx urban mesh network increases public safety and community quality of life.
Specific areas of development interest:
Traffic and incident monitoring
ACN (automatic crash notification)
Low or no power reactive RFID technology to notify transport operators and emergency services when automobiles collide into guardrails, signage, bridge structures and other fixed roadside transport assets within minutes of an event Variable Message signage (VMS) VMS technology is rapidly becoming an international staple for roadside management, using RFID as the edge component your sensor technology will provide automatic cautionary instructions on delineation, speed and guidance or approaching critical risk advisories such as ice, fog, surface water, accidents and height restrictions for heavy vehicles.
Here is your opportunity to do something for the environment we are looking for technology to monitor water quality for chemicals, gases, substance and compound contaminants in our ports, water ways, estuaries, creeks, rivers and sewers.
Telepathx Residential & Industrial monitoring
Residential and industrial alarm monitoring is another ancillary service that will be delivered from the Telepathx urban mesh network. Particular interest is in consumer and industrial alarm technology relating to the detection of smoke, water, fire, gas, chemical and intrusion detection technology.
Wireless sensor developers are strongly encouraged to take part in this land mark event as a way of showcasing there technology to global markets and governments. Interested parties should register interest by contacting Telepathx Ltd at (61) 395511155 or sending an email email@example.com // Printed material may be sent to 38/632 Clayton Road, Clayton South, Victoria 3169 Australia
