一种基于多频生物电阻抗法的人体腹部脂肪检测系统的设计
A Design Based on Bioimpedance Spectroscopy Method in Human Abdominal Adipose Measurement System
摘要
Abstract
Human body's abdominal fat content can be divided into SFA( Subcutaneous Fat Area) and VFA( Visceral Fat Area)according to the depth,two kinds of fat content has certain effects on human health,in order to avoid the measurement of different depth of abdominal fat content caused by their mutual interference. This paper introduces a design based on the bioimpedance spectroscopy method BIS ( bioimpedance spectroscopy ) for the measurement of the human abdominal fat device. The device adopts four electrodes and multi-frequency bioelectrical impedance measurement system, mainly including the programmable signal generator module and the amplitude and phase detection module. According to the selection of the best relative fixed electrode position and the appropriate measurement scheme,the corresponding depth of abdominal fat content can be calculated. The result indicates that the system is stable and reliable, with sufficient accuracy, precision and good repeatability. So for the traditional impedance analysis measurement systems with BIS which needs only measuring a single depth abdominal fat content has an important reference meaning help.关键词
