Stay one step ahead: 6-axis IMU with embedded sensor fusion, Artificial Intelligence and Qvar sensing

An advanced inertial module with intelligent on-chip functionalities for high-end applications, including UI support


With a triple core, 6-axis architecture, the LSM6DSV16X Inertial Measurement Unit can handle advanced processing in the edge, making it ideal for advanced 3D phone mapping, context awareness in laptops and tablets, reliable and precise gesture recognition in AR and VR headsets, and always-on tracking in wearables.

LSM6DSV16X enables sensor fusion low power (SFLP), on-the-fly self-configuration, and AI algorithms. The IMU performs the data processing directly in the MEMS sensor, which enables significant energy savings in the system.

Thanks to its triple sensing core, the LSM6DSV16X can address the needs of user-interface controls and optical/electronic image stabilization (OIS/EIS).

Stay one step ahead with the LSM6DSV16X, enabling the Onlife Era.

Personal electronics

Did you know that carrying a laptop in a backpack that is not properly shut down can drain your battery? ST’s new 6-axis sensor is the first of its kind to offer context recognition, bringing a whole new level of experience to users, while preserving the battery.




While 3-axis MEMS sensors enable various basic functionalities, such as wake up modes or screen orientation, ST’s 6-axis motion-tracking sensor provides additional information on the environment. Developers can now create new services or improve existing ones, without draining the battery.



Do not take customers for granted! After years of double-digit growth, questions remain about how reliable wearables are. Ultralow-power, ST’s always-on 6-axis sensor has been designed to boost accuracy in power-constraint applications, including wearables.




Easily enter the metaverse and create lifelike animated avatars with ST’s new AI-enabled 6-axis motion sensor. Build a fully immersive experience with ST’s ecosystem and replicate body gestures in real time.
