Geo-magnetic sensors: propelling disruptive consumer apps
According to iSuppli, the outlook of the MEMS market for 2010 and beyond is good, and the MEMS market is expected to return to double-digit growth in 2010 and an overall CAGR of 12.2 percent for the period covering 2009-2013.
MEMS sensors are well recognized to be the key building blocks for the implementation of disruptive applications in consumer devices. Consumer devices—from game consoles to mobile phones and from laptops to white goods—have already benefited in the recent years from the usage of low-g accelerometers for the implementation of motion-activated user interfaces and enhanced protection systems. It is now the turn of MEMS gyroscopes and geo-magnetic sensors, whose usage is propelling a new wave of compelling applications, to be discussed.
Much has been already written about the technology behind MEMS accelerometers, sensors capable of detecting linear accelerations. Accelerometers will thus be barely touched in this article, leaving the space to gyroscopes, geo-magnetic sensors and to devices capable of providing multiple degrees of freedom to sensing.
