Health and Fitness Wearable Sensors

Overview

MotionFit Wireless SDK wristband and InvenSense MotionFit App

Integrated MotionTracking™ devices, with accelerometers, gyroscopes and other motion sensors, are expected to be incorporated into activity monitors, fitness devices, pedometers, golf and tennis swing analysis tools, and sports kinetics applications. Health and Fitness wearable sensors can now stream data to smartphones via low-power wireless interfaces and deliver real-time data to a wide variety of smartphone health and fitness applications. Leveraging wireless connectivity, powerful application processing and storage capabilities in today’s smartphones, wearable sensors are finding new use cases such as remote patient monitoring, where the patient’s motion data analysis can be sent directly to the physician. The introduction of InvenSense’s MotionTracking™ devices further enable this market, with integration of 6 axis (3-axis accelerometer and 3-axis gyroscope) or 9-axis (addition of eCompass) motion sensors offering a small form factor and low power consumption. InvenSense’s MotionTracking™ devices, with embedded MotionFusion™ software, are capable of providing higher accuracy body movement detection versus traditional accelerometer-only wearable designs. 6 and 9-axis MotionTracking™ solutions have the ability to accurately identify and characterize a broad range of fitness activities allowing for very accurate calculations of, for example, calorie burn rate over time.

Our 6-axis and 9-axis MotionTracking™ devices are optimized for embedded microcontroller subsystems with small memory and processing resources. Complicated MotionFusion™ and sensor calibration tasks can be offloaded to the Digital Motion Processor™ (DMP) on the MPU, reducing MIPS and memory requirements on the microcontroller saving cost and power. The solution alleviates the challenges faced by developers by allowing them to focus on uniquely differentiated solution development, not the underlying complexities of processing raw sensor data.
