Bosch is now the top MEMS supplier with a production of more than 4 millions MEMS per day. This strong growth is due to both consumer applications and automotive applications.

With a size of only 7.5mm² (3×2.5mm), the BMI160 is the smallest 6-Axis IMU MEMS on the market and features 60% volume reduction compared to previous BMI055. This size reduction has been made possible by the use of a new design and process for the MEMS Gyro and by the integration in one ASIC die for the control of both MEMS. The BMI160 is a 16-bit digital resolution accelerometer and gyroscope well suited for applications requiring extremely small form factors.

Bosch has worked on the power consumption with a low power mode for the significant motion and step detector functions, using a “7-axis” accelerometer. Moreover, the unique ASIC die can perform the fusion of the data from the accelerometer and gyroscope with those from an external sensor.

The report is including a detailed technical and cost comparison with the previous generation BMI055 and the state of the art 6-Axis MEMS IMU from Invensense.
