Introduction to BMI085
The BMI085 is a high-performance 6-axis Inertial Measurement Unit (IMU) launched by Bosch Sensortec at electronica China in Shanghai. This powerful IMU integrates a 3-axis, 16-bit MEMS acceleration sensor and a 3-axis, 16-bit MEMS gyroscope in a single compact package, making it ideal for demanding virtual reality (VR) and augmented reality (AR) applications.
Key Features and Benefits
The BMI085 is designed to offer a particularly low-drift gyroscope and a low-noise accelerometer, significantly reducing the unpleasant motion sickness effect in VR and AR applications. Its ultra-precise instantaneous detection of head movements reduces time lag to an almost imperceptible minimum, allowing users to have interaction their virtual environments for longer periods without requiring frequent breaks. According to Stefan Finkbeiner, CEO at Bosch Sensortec, "High performance AR/VR applications demand extremely sensitive, precise, robust and responsive motion sensors. With the Bosch BMI085, the user can enjoy a rather more realistic and nice experience within the exciting worlds of virtual and augmented reality, without the negative physical effects."
Accuracy and Low Latency
The exceptionally low latency of the brand new BMI085 enables headset manufacturers to eliminate image drifts and deliver a real real-life experience. The IMU delivers a low motion-to-photon latency of lower than 3 ms and achieves near perfect stability in environments with hot temperature fluctuations, further improving accuracy. This is critical in today’s lightning fast high-definition AR/VR applications.
Outstanding Temperature Stability
The sensor’s accelerometer has rock-solid temperature stability, delivering a powerful low temperature coefficient offset (TCO) of typically lower than 0.2 mg/K and temperature coefficient sensitivity (TCS) of only 0.002 %/K. Bias instability of the gyroscope is usually below 2 °/h. The gyroscope of the BMI085 encompasses a robust closed-loop analog-to-digital conversion mechanism, which ensures low drift characteristics even in high-fluctuation temperature environments.
Technical Specifications and Availability
The BMI085 is housed in a compact 3.0 x 4.5 x 0.95 mm³ package and is pin-to-pin compatible with Bosch’s BMI055 IMU, making design migration to the brand new BMI085 extremely smooth and effortless. Bosch has greater than 20 years of experience within the fields of inertial MEMS sensors and accelerometers, and brings automotive level reliability and performance to the patron electronics sensor space. The BMI085 was available for distributors end of May 2018. For more information, please visit the official website or social media channels.
Conclusion
In conclusion, the BMI085 is a robust and compact IMU that gives high-performance motion sensing capabilities for demanding VR and AR applications. Its exceptional accuracy, low latency, and outstanding temperature stability make it an excellent selection for headset manufacturers and developers. With its robust design and automotive level reliability, the BMI085 is poised to revolutionize the world of virtual and augmented reality, providing users with a more immersive and realistic experience.
