This analyzer measures body composition by sending a low‑amplitude alternating current through custom‑shaped electrodes and calculating impedance to derive fat‑free mass, total body water, and segmental fat percentages. Electrode geometry, drive frequency, and current magnitude are tailored to the target measurement site, allowing repeatable results across diverse populations.
Technical Specifications
Key performance parameters are presented below; values are typical for a standard configuration and can be adjusted per project requirements.
| Parameter | Typical Value | Adjustable Range / Notes |
|---|---|---|
| Drive Frequency | 5 kHz – 500 kHz | Selected per tissue depth; customizable in 1 kHz steps |
| Excitation Current | ≤ 100 µA rms | Safety‑limited; adjustable down to 10 µA for sensitive subjects |
| Impedance Measurement Resolution | 0.01 Ω | Enables detection of <0.5 % fat change |
| Electrode Material Options | Stainless steel 316L, medical‑grade titanium, conductive polymer | Chosen based on biocompatibility, corrosion resistance, and cost |
| Sample Rate | 1 kS/s per channel | Supports real‑time tracking during exercise protocols |
Applications
The analyzer serves industries where precise, repeatable body‑composition data informs decision‑making, rather than merely listing sectors.
- Sports science labs use segmental data to monitor muscle‑fat distribution in athletes during periodized training.
- Clinical nutrition programs rely on multi‑frequency impedance to track fluid shifts in dialysis patients.
- Occupational health assessments incorporate the device to evaluate ergonomic risk linked to adipose distribution.
- Research studies on aging utilize the analyzer’s high resolution to detect sarcopenia‑related changes over months.
- Corporate wellness programs deploy portable versions for on‑site employee health screening.
Customization Options
Beyond electrode shape, the system adapts to mechanical, electrical, and software constraints of the host environment.
- Electrode geometry: adjustable strap length, snap‑on pads, or embedded arrays for specific anatomical sites.
- Housing: IP‑rated enclosures (IP65), portable battery‑operated modules, or rack‑mount chassis.
- Signal conditioning: programmable gain amplifiers, optional notch filters for 50/60 Hz line noise rejection.
- Output interfaces: USB‑CDC, Bluetooth Low Energy, Modbus RS‑485, or analog voltage (0‑5 V) for PLC integration.
- Firmware: selectable calculation algorithms (e.g., Kotler, Deurenberg) and custom data logging intervals.
Quality Assurance
Each unit undergoes a three‑stage verification process to confirm measurement accuracy and long‑term stability before shipment.
- Impedance traceability: compared against a calibrated precision resistor network (±0.1 %) at multiple frequencies.
- Electrode contact validation: automated pressure‑sweep test ensures impedance variation <2 % across the specified force range.
- Environmental cycling: temperature (−10 °C to +50 °C) and humidity (10 %–90 % RH) exposure for 48 h, followed by repeatability check.
Frequently Asked Questions
Can electrode dimensions be customized for specific measurement sites?
Yes. Electrode length, width, and contour are defined per drawing; typical adjustments range from 20 mm to 120 mm for limb segments and up to 200 mm for torso applications.
What information is required before a quotation can be issued?
Target measurement anatomy, desired frequency range, required output interface, estimated annual volume, and any regulatory certifications (e.g., IEC 60601) needed for the end market.
Which materials are available for the electrodes and housing?
Electrodes: 316L stainless steel, titanium grade 2, or silver‑filled silicone. Housing: ABS‑PC blend, aluminum alloy, or medical‑grade polycarbonate, each selectable for IP rating and weight constraints.
How is quality inspected for each production batch?
Every lot receives impedance traceability testing, electrode contact force validation, and a sample of units undergoes full environmental cycling as described in the Quality Assurance section.
