MEMS, Who Will Win the Prize?
According to the Yole development analysis, Texas Instrument ranks the first in 2011 MEMS
revenues with a revenue of $913 million. Following is STMicroelectronics, which achieves a 42%
jump in MEMS sales from 2010 to $907 million. What’s more, ST is also a leading foundry
supplier of MEMS components. The top 30 companies in the figure accounted for almost 80
percent of total MEMS packaged device sales worldwide.
Where should MEMS go?
It is reported that high volume consumer applications will continue to dominate the MEMS market
but it will continue to evolve rapidly. While as more and more MEMS sensors are showing up in
mobile devices, the focus of MEMS design has begun shifting from discrete MEMS components
to MEMS sensor data integration. MEMS sensors can be easily to be found in today’s smart
phones and tablets include accelerometers, magnetometers, gyroscopes and barometers. Growth is
now coming from combos of accelerometers and magnetometers and from combos of
accelerometers and gyros, which started to ship in volume last year, Companies who make only
accelerometers will have to change.

Who will determine the sensor architecture, where the processing will reside and the
motherboard-level sensor fusion architecture?” Throwing more sensors into a mobile device is one
thing. But how to minimize the associated power consumption is another.
Just designing a number of MEMS sensors into one’s system is hardly enough to improve a
system’s power consumption, flexibility in system designs, sensor data or reliability and apps’
performance.
Earlier this year, Freescale Semiconductor introduced its own sensor fusion algorithms called
Xtrinsic for electronic compass. Electronic compass applications combine magnetometer-provided
headings with corrections from inertial sensors that compensate for stray magnetic fields. And
Freescale is offering its sensor fusion algorithms as a free download for its MEMS sensor users.
Meanwhile, STMicroelectronics last fall rolled out its own sensor fusion algorithms called
iNEMO Engine Sensor Fusion Suite. According to ST, its iNEMO Engine can be combined with
ST’s iNEMO Inertial Modules to create complete and customizable hardware/software multi-axis
MEMS sensor solutions for enhanced motion and accurate heading recognition.
