9-Axis MEMS Motion SensorsOVERVIEW Note: See our 9-axis development kits for our most up-to-date 9-axis solutions. The 9-Axis family of parts are the world’s leading 9‑axis MotionTracking® devices designed for battery operated, high-performance consumer electronics products. This product family incorporates the same market proven MotionFusion™ and run-time calibration that is supported in InvenSense’s market‑leading 6‑axis family of products. This solution has shipped in millions of units and has been very well market validated. 9-Axis MotionTracking has become a key function in many consumer electronics devices including smartphones, tablets, and wearables. The size advantage of the integrated 9‑axis devices versus a discrete solution is compelling for space constrained products such as smartphones and wearable sensors. InvenSense’s 9-Axis devices combine a 3‑axis gyroscope, 3‑axis accelerometer and 3‑axis compass in the same chip together with an onboard Digital Motion Processor™ (DMP™) capable of processing the complex MotionFusion algorithms. |
