A wireless bioimpedance device for abdominal fatness monitoring

Abstract A wireless bioelectrical impedance (bioimpedance) device for assessing abdominal fatness is presented. The proposed device is based on a bioimpedance measurement circuit designed in 0.35-μm CMOS technology and a commercially available ZigBee device, which provides reliable wireless communication. The traditional techniques for measuring bioimpedance signals are either time-consuming or associated with high cost, high power consumption, and large board space and, hence, are not suited to design an unobtrusive monitoring device. A magnitude-ratio method able to evaluate visceral fat accumulation with low influence of subcutaneous fat volume while providing a cost-effective solution is proposed. The presented device achieves less than 1% relative error over the 100-Ω range with a current of 10 μA at 50 kHz.
