STMicroelectronics develops a motion and position sensor with MEMS technology

STMicroelectronics' nine-axis motion and position sensor is ideal for gesture control applications, indoor navigation, augmented reality and healthcare environment.

STMicroelectronics has developed the LSM9DS1 module to detect motion and position. With improvements in performance and efficiency in an encapsulation of 3.5 X 3 Mm (A 35% less than previous generations), provides the functions required in gesture control tasks, indoor navigation and augmented reality.

LSM9DS1 integrates three-axis accelerometer, three-axis gyroscope and three-axis magnetometer, all manufactured with ST's MEMS process technology. These sensors detect linear acceleration, angular ratio and magnetic field to provide motion and position sensing data. The new module is integrated and synchronized to provide true nine-degree-of-freedom sensing (degree-of-freedom) instead of separate, uncoordinated data entries.

ST's MEMS process technology also helps minimize energy consumption, in combination with intelligent management modes. The typical operating current is at 2 Ma.

Its tiny size and low power consumption of ST's low-noise sensor technology, helps increase the use of portable devices by extending battery life between recharges. In addition, Higher position resolution increases stability and accuracy of applications such as remote Smart TVs, portable sports systems or medical sensors.

"This tiny nine-axis module benefits from our latest MEMS technology to enable a wide variety of position sensing and motion tracking applications in next-generation wearable devices.", says Benedetto Vigna, Executive Vice President and General Manager, Analog Division, MEMS & Sensors de STMicroelectronics.

The device has a magnetometer resolution of one 30 percent higher, consequence of the use of ST's low noise process technology, as well as a 20 percent lower. On the other hand, each sensor can be powered individually with automatic wake-up, providing smarter management.

Support for the IMU LSM6 family (Inertia Measurement Units) ST's six-axis simplifies updating or scaling existing designs by incorporating magnetic field detection into functions such as e-compass and orientation. Developers can now create products that combine a six-axis LSM6 device with a discrete magnetometer to save space and provide an integrated, LSM9DS1-based solution..

These enhancements allow any portable device, as smartphones, Tablets, Drivers, smart glasses... Support motion tracking and orientation functions with maximum accuracy.
