In stock at distributor Mouser Electronics is the LSM6DSV16BX motion and bone-conduction sensor from STMicroelectronics.

Combining a three-axis digital accelerometer and three-axis digital gyroscope, the sensor provides advanced functions for applications including wearable and hearable devices, motion tracking and gesture detection, Internet of Things (IoT) and connected devices, and bone conduction for vibration detection.

The sensor integrates an audio accelerometer, Qvar sensor, and UI sensor in a compact package. The device's superior performance and limited form factor make it an ideal choice for small devices, including headsets and earbuds.

It includes a triple core for processing acceleration, angular rate, and Qvar sensing data on separate channels.

The "always-on" sensor features low power consumption of just 0.95 mA in combination with high-performance mode, ensuring uninterrupted performance for both the accelerometer and gyroscope. The LSM6DSV16BX device also includes a machine learning core with exportable features and filters, allowing the device to be used in AI applications.

The sensor is supported by the STEVAL-MKI234KA evaluation kit, which in conjunction with the STEVAL-MKI109V3 motherboard, provides a demonstration platform for the device. The evaluation kit supports a downloadable graphical user interface and dedicated software routines for customised applications
