Frequently Asked Questions (FAQ)
Here you can find answers to frequently asked questions about iBodyinfo’s body composition analyzer modules, technical solutions, and services. We aim to provide clear, professional technical and business information to help you evaluate our offerings. If you can’t find the answer you’re looking for, please feel free to contact us.
A: Our core advantage lies in our objective algorithm, free from empirical formulas, and our professional-grade measurement precision. We have mastered core Bioelectrical Impedance Analysis (BIA) technology, from multi-frequency to 8-electrode segmental measurement, enabling independent analysis of muscle and fat in the limbs and trunk. Our modules directly output multi-dimensional, precise data—including PBF, SMM, visceral fat, and body water—making them the ideal technical core for your professional-grade devices.
A: Our modules operate on the industry gold standard principle of Bioelectrical Impedance Analysis (BIA). When a user operates the device, the module sends a safe, imperceptible, low-level electrical current through the body via electrodes. Because different body components like muscle and fat have different conductivity, they impede the current differently. Our core algorithm captures these precise impedance variations and accurately translates them into easy-to-understand health metrics like percent body fat and muscle mass.
A: Both are high-performance 8-electrode modules, with the main difference being their measurement frequencies and target applications:
BCM-MF270 (Professional): Uses dual-frequency measurement, striking a perfect balance between performance and cost. It is powerful and stable, ideal for commercial smart scales and analyzers that require high-quality measurement within a controlled budget.
BCM-MF570 (Flagship): Utilizes quad-frequency measurement to provide the most detailed segmental and intra/extracellular water data. Its superior accuracy makes it the top choice for professional medical, high-end fitness, and scientific research applications.
A: Our modules can output a comprehensive body composition report, including but not limited to: Weight, BMI, Percent Body Fat, Muscle Mass, Body Water, Skeletal Muscle Mass, Visceral Fat Level, BMR, and over 20 other core metrics. Cross-validated against industry gold-standard devices, our results are highly correlated and demonstrate excellent accuracy and repeatability on key metrics, fully meeting the demands of professional applications.
A: Yes. Our flagship models (like the BCM-MF570) are designed with a dedicated height interface that seamlessly connects to TTL-compatible ultrasonic modules. This allows for the simultaneous acquisition of height and body composition data in a single measurement, enabling a truly integrated human data analysis.
A: Yes, providing turnkey OEM/ODM solutions is one of our core services. As a professional BIA module manufacturer, we not only supply standard modules but also offer fully integrated hardware and software customization based on your brand and functional needs—from PCBA design and algorithm integration to app data interfaces—helping you rapidly launch your own branded smart health devices.
A: We handle the complexity so you can enjoy the convenience. Our measurement modules feature a “plug-and-play” design and are easily integrated into your mainboard via a standard TTL serial port. We provide comprehensive development documents, communication protocols, and PC-based debug tools. Furthermore, our technical support team offers full-cycle assistance to ensure your R&D team completes the integration smoothly and quickly.
A: It’s simple. Just submit your requirements through our website’s contact page, or contact our sales team directly via phone or email. Our engineers will have an in-depth discussion with you, provide detailed product information, a quote, and arrange for sample testing. Once we partner, you will receive dedicated technical support to ensure your project’s success.
