Kionix Announces Breakthrough Micro-Amp Magnetic Gyro Solution for Consumer Electronics Applications

Ithaca, NY—Kionix, Inc., a leading supplier of MEMS inertial sensors and software solutions, today announced the KMX61G – a high performance accelerometer-magnetometer sensor with industry-leading sensor fusion software that delivers the world’s first highly accurate gyro emulation using just 550µA of power.  This represents dramatic savings in power compared to traditional gyros, providing new options for consumer electronics product designers.

Now a single 6-axis device can provide 9-axis accelerometer, magnetometer (e-compass) and gyro outputs with a power profile that enables applications previously unreachable using traditional 9-axis solutions. 

“We see many applications in mobile devices that can benefit from gyroscope functionality but do not require the extreme performance of a traditional gyro.” said Jeremie Bouchaud, Director & Sr. Principal Analyst, iHS iSuppli.  “The magnetic gyroscope can meet these needs well while offering power, cost and size benefits that are very attractive.”

In addition to Kionix’s proprietary calibration and sensor fusion algorithms, the KMX61G includes a range of capabilities to enable precise control of the sensor including 512-byte FIFO buffer with watermarking, embedded temperature sensor and a low-power, embedded motion wake-up function.

With applicability to the large and rapidly growing smartphone, tablet, and health and fitness devices market, the KMX61G is well-suited to help design engineers achieve new levels of product performance.

“Customers have told us they would like to include gyro capabilities in their product designs, but in many cases are unable to due to power, size or cost constraints.” said Scott Miller, Vice President of Engineering, Kionix.  “We are excited that through the combination of high-performance hardware and innovative software the KMX61G delivers breakthroughs in all of these areas, providing our customers with a range of new design possibilities.”

For customers only requiring high performance e-compass capabilities without a gyro output, Kionix is also introducing the KMX61, a 6-axis e-compass device with auto-calibration software.  The KMX61 delivers high sensitivity (0.05 µT/count) with stability over temperature (± 0.05 %/ºC) and is well-suited for a range of smartphone, tablet and health and fitness applications.
