Motion and bone-conduction sensor offers superior performance

14-04-2023 | Mouser Electronics | Test & Measurement

Mouser is now stocking the STMicroelectronics LSM6DSV16BX motion and bone-conduction sensor. Integrating a three-axis digital accelerometer and three-axis digital gyroscope, the sensor supplies advanced functions for applications, including wearable and hearable devices, motion tracking and gesture detection, IoT and connected devices, and bone conduction for vibration detection.

The motion and bone-conduction sensor integrates an audio accelerometer, Qvar sensor, and UI sensor in a compact package. The device's outstanding performance and limited form factor make it an excellent option for small devices, including headsets and earbuds. The sensor includes a triple core for processing acceleration, angular rate, and Qvar sensing data on separate channels. The 'always-on' sensor provides low power consumption of only 0.95mA and high-performance mode, ensuring uninterrupted performance for the accelerometer and gyroscope. The device also incorporates a machine learning core with exportable features and filters, enabling the device to be used in AI applications.

The motion and bone-conduction sensor is supported by the STEVAL-MKI234KA evaluation kit, which in conjunction with the STEVAL-MKI109V3 motherboard, offers a demonstration platform for the device. The evaluation kit supports a downloadable GUI and dedicated software routines for customised applications.
