Smart, ultra-low power IMU is optimized for wearables


BOSCH SENSORTEC BMI270 ultra-low power smart Inertial Measurement Unit (IMU) specifically targeted at wearable applications provides an improved accelerometer offset and sensitivity performance, enabled by firm’s newest MEMS process technology. Device includes intuitive gesture, context and activity recognition with an integrated plug-and-play step counter. As an ultra-low power unit, device extends system battery life by handling multiple activity tracking, step counting and gesture recognition functions independently of the main system processor, without having to wake it up. These processor-independent functions include tasks such as sending an interrupt when a certain number of steps is reached, or geofencing to activate GPS when the user stands up and starts walking. Powerful, accurate gesture and activity recognition features therefore run in the ultra-low power domain, with current consumption of 30μA.
