Bosch Sensortec offers innovative sensing solutions to enable smart wearable and hearable applications with exciting features

Bosch Sensortec enables wearable and hearable applications with ultra-low power, accurate and highly integrated sensing solutions. The sensor portfolio offers a broad range specially designed for wrist-worn wearables, such as smart watches, hearable devices and smart clothes: accelerometers (BMA456, BMA400), absolute orientation sensors (BMX160), inertial measurement units (BMI270) and pressure sensors (BMP388).

The BMA456 hearable accelerometer is the industry’s only accelerometer with optimized hearable features integrated in one sensor and complements the existing BMA456 wearable variant. Manufacturers can now design smaller and more accurate hearables at lower power while increasing the devices’ performance. The new BMA456 accelerometer variant integrates hearable-specific gestures for intuitive user interactions such as tap, double-tap and triple-tap.
