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." Get Full Details About This Report >> |
