IMU100-BL Empowers Smart Rehabilitation Devices with High-Precision Posture Monitoring

IMU100-BL Enables High-Precision Posture Monitoring in Smart Rehabilitation Equipment

With the rapid development of smart medical and rehabilitation technologies, human motion capture and posture monitoring have become core functions of rehabilitation equipment. Many rehabilitation equipment manufacturers are developing next-generation limb rehabilitation training systems aimed at achieving accurate motion recognition and real-time feedback to improve rehabilitation outcomes.

However, these projects have encountered numerous bottlenecks during product development.

Several key issues arose during testing:

Unstable posture data: During dynamic training, significant drift in device output led to inaccurate motion assessment, directly impacting the scientific validity of rehabilitation training.

Insufficient real-time performance: Limited data update frequency prevented immediate feedback, severely affecting user experience.

High algorithm development complexity: Posture calculation involves the fusion of gyroscope, accelerometer, and magnetometer data, requiring complex filtering algorithms. This results in long development cycles and high debugging costs.

Wireless and portability limitations: The customer required a wireless and portable solution, but their existing system's wireless transmission stability was insufficient to meet practical application needs.

These problems caused significant project delays, preventing the product from entering mass production as planned.

RION provides the following solutions:

To meet customer needs, we have launched the IMU100-BL Miniature Attitude and Heading Reference System (AHRS), enabling rapid technology upgrades.

Integrated nine-axis sensors: accelerometer, gyroscope, and magnetometer

Built-in attitude fusion algorithm: Kalman filtering and temperature compensation for highly stable attitude output

Plug-and-play functionality: Customers can directly obtain accurate attitude angles without developing complex algorithms.

For real-time performance, the IMU100-BL supports 100Hz high-frequency output, enabling instant response to human movement and significantly improving the interactive experience in rehabilitation training.

In terms of wireless functionality, the IMU100-BL is equipped with a Bluetooth 5.1 module, supporting BLE protocol and 2.4GHz adaptive frequency hopping. Under line-of-sight conditions, its transmission distance reaches up to 40 meters and supports multi-device synchronization, significantly improving flexibility and scalability.

Furthermore, this module features excellent vibration resistance and low-noise output, ensuring stable data transmission even in complex environments.

In terms of development, the IMU100-BL supports parameter configuration and IAP (In-Application Programming) firmware upgrades, facilitating customer adjustments to system parameters and enabling rapid secondary development.

Advantages of the RION Solution:

Significant improvements were achieved after adopting the IMU100-BL:
