BioX FMG FAQ: Frequently Asked Questions

This resource is designed to help researchers and engineers get the most out of our FMG sensor bands. Whether you are troubleshooting your Python API or curious about battery specs, this BioX FMG FAQ covers the essentials for high-performance wearable sensing.

Getting Started & Setup

What is included in the box? 

Each package contains one (1) BioX AAL-Band 2.0 unit and one (1) 0.5m USB 2.0 Type-A to Micro-B charging cable.

How do I begin using the AAL-Band? 

  • Initial Charge: Fully charge the band for at least 6 hours before the first use.

  • Bluetooth Pairing: Enable Bluetooth on your Windows PC and pair the device.

  • Software Installation: Install the BioX Desktop Client to begin streaming and visualizing data.

How do I pair the device via Bluetooth?

The AAL-Band uses standard Bluetooth protocols. For a step-by-step guide on connecting peripherals to Windows, please refer to the Official Microsoft Support Guide.

Does the band require any skin preparation or conductive gels?

The AAL-Band 2.0 is designed for a forearm circumference between 22cm and 25cm to ensure optimal sensor contact and comfort.

 

Calibration & Technology

How does the AAL-Band 2.0 handle motion artifacts compared to sEMG?

Unlike sEMG, FMG measures physical muscle pressure via an array of 8 FSR sensors. Combined with a highly sensitive IMU, this bi-modality makes the AAL-Band significantly more resistant to electrical interference and skin-movement artifacts.

Can I use multiple bands simultaneously on the same subject?

Yes. Our software supports synchronized data streaming from multiple bands for comprehensive musculoskeletal analysis of different limb segments simultaneously.

How do I calibrate the AAL-Band?

To calibrate, maintain a closed-fist gesture at your desired intensity and press the Calibrate button in the software. Once the calibration indicator turns green, you may relax your hand. The sensor will now use that specific muscle contraction level as its reference point.

What core technology does the AAL-Band utilize?

The AAL-Band utilizes patented Force Myography (FMG) to monitor muscle contraction intensity and an integrated 9-DOF IMU sensor to track limb orientation, gravity vectors, angular velocity, and acceleration.

How many gestures can the system detect?

Using raw FMG data alone, the system can reliably detect 10 distinct gestures. By integrating IMU motion data, the potential for complex, custom gesture recognition is significantly expanded.

Technical Specs & Connectivity

What is the maximum sampling rate of the sensors?

The AAL-Band 2.0 features high-speed data acquisition with a sampling rate optimized for real-time limb motion detection, ensuring high-fidelity signal capture for biomechanical analysis.

Can I integrate BioX sensors with Python or MATLAB?

Yes. We provide a comprehensive SDK with native support for Python, C++, and MATLAB, allowing for seamless real-time data streaming and offline analysis in your preferred research environment.

Is the software compatible with ROS (Robot Operating System)?

Yes, the BioX ecosystem offers dedicated integration for ROS, making it ideal for real-time control applications in robotics, exoskeletons, and shared autonomy research.

What is the latency between muscle contraction and data output?

The system is optimized for real-time applications, achieving ultra-low latency, which is critical for instantaneous gesture recognition and reactive assistive devices.

Is the data encrypted during wireless transmission?

The AAL-Band uses Classic Bluetooth SPP for reliable point-to-point data transmission, ensuring a robust connection between the wearable unit and your workstation.

Can the AAL-Band be used without a Bluetooth connection?

No. The AAL-Band 2.0 is designed as a wireless wearable and requires a Bluetooth connection for all data transmission and software interaction.

What is the maximum wireless range?

The AAL-Band has a reliable wireless range of up to 50 meters in an open environment.

Can I export and collect raw data?

Yes. Users can collect and export both raw Force Myography (FMG) and IMU data. Comprehensive instructions for data logging are available in the User Guide.

Battery Life & Charging


What is the expected battery life and charging time?

  • Charging Time: A full charge requires approximately 6 hours.

  • Operating Time: A fully charged battery provides up to 4 hours of continuous active use.

How do I charge the device?

Charging is done via a standard Micro-USB cable (5V). Please note that the band should not be operational while charging to protect the battery life.

How many hours of continuous data collection does the battery support?

The AAL-Band 2.0 provides approximately 4 hours of continuous use on a full single charge, supported by dynamic power scaling features.

Hardware & Compatibility

Does the AAL-Band come in different sizes?

The Developer Edition is currently optimized for a forearm circumference of 22–25 cm. The adjustable medical-grade strap ensures a secure fit within this range.

Is the device compatible with external hardware?

Yes, the AAL-Band is designed with a modular housing that allows for the attachment of Lego-compatible components, making it ideal for rapid prototyping in robotics and education.

Is the AAL-Band waterproof?

No. The AAL-Band is a precision electronic instrument and is not waterproof. Avoid exposure to moisture or high-humidity environments.
