STMicroelectronics Introduces dual-accelerometer AI-enabled sensor for activity tracking and impact detection

Semiconductor MEMS based sensor leader STMicroelectronics launched the LSM6DSV320X, an inertial measurement unit (IMU) combining activity tracking and high-impact sensing in a 3mm x 2.5mm package. The device integrates two accelerometers, one measuring up to ±16g for activity tracking and another up to ±320g for impact detection, alongside a ±4000dps gyroscope, all fully synchronized.
The sensor features an embedded machine-learning core (MLC) for on-device AI processing, a finite state machine (FSM) for motion tracking, and Sensor Fusion Low-Power (SFLP) technology for spatial orientation. Adaptive self-configuration (ASC) enables real-time setting adjustments based on motion patterns, reducing power consumption without host processor intervention. The Motion XLF software library, provided free with the X-CUBE-MEMS1 package, fuses data from both accelerometers to enhance accuracy across low- and high-g ranges.
Applications include smartphones, wearables, gaming controllers, smart tags, and consumer medical devices, as well as industrial safety equipment and structural health monitors for buildings and bridges. The sensor supports slim, lightweight designs for wearable and attachable devices. Graphical tools, including MEMS Studio and ST AIoT Craft, are available for evaluation, configuration, and integration with STM32 applications. The LSM6DSV320...
