Inquire NowThis device combines ultrasonic time‑of‑flight ranging with bio‑impedance analysis to provide non‑contact height measurement and estimated body‑fat percentage in a single scan.
An ultrasonic transducer emits a short pulse toward the subject’s crown; the reflected echo is timed to calculate distance with millimeter resolution. Simultaneously, four surface electrodes pass a low‑amplitude alternating current through the torso, measuring impedance that correlates with total body water and, via established algorithms, estimates fat mass.
The two data streams are fused in firmware to output height (cm) and body‑fat (%) with a typical repeatability of ±0.5 cm and ±1.0 % respectively.
| Parameter | Typical Value | Unit | Notes |
|---|---|---|---|
| Height measurement range | 80 – 220 | cm | Adjustable via firmware |
| Height resolution | 0.1 | cm | Echo processing |
| Height accuracy | ±0.5 | cm | At 25 °C, still subject |
| Body‑fat measurement range | 5 – 50 | % | Based on bio‑impedance |
| Body‑fat accuracy | ±1.0 | % | Typical adult population |
| Sampling rate | 10 | Hz | Continuous output |
| Power consumption | < 2 | W | USB‑C supply |
| Operating temperature | 0 – 45 | °C | Non‑condensing |
| Output interfaces | USB‑C, UART, optional Bluetooth 5.0 | – | Configurable |
Each unit undergoes a three‑stage verification: (1) ultrasonic transducer impulse response is measured against a calibrated reference target; (2) bio‑impedance front‑end is checked with precision resistors to confirm gain and phase accuracy; (3) functional test validates height and fat outputs on a volunteer cohort against gold‑standard stadiometer and DXA reference. Units that exceed the specified tolerances are rejected before packaging.
