IMU tracks high-G impacts and motion

The LSM6DSV320X inertial measurement unit (IMU) from ST features dual accelerometers for activity tracking up to 16 g and impact detection up to 320 g. To support edge computing, it integrates a machine-learning core for context awareness with exportable AI features, along with embedded functions such as a finite state machine for configurable motion tracking.

Housed in a compact 3×2.5-mm module, the IMU suits applications ranging from wearables and consumer medical devices to smart home and vehicle crash-detection systems. In addition to the 3-axis accelerometers, it includes a gyroscope with a range of up to ±4000 dps. All three sensors are fully synchronized to simplify application development.

Other features include an embedded sensor fusion low-power algorithm for spatial orientation and an adaptive self-configuration (ASC) function. With ASC, the sensors automatically adjust their settings in real time when a specific motion pattern or machine-learning core signal is detected—without requiring host processor intervention.

In production now, the LSM6DSV320X is supported in the Edge AI Suite and will be added to AIoT Craft by the end of 2025.
