生体複素インピーダンスの実時間計測法  [in Japanese] A Real Time Measuring Method for Complex Impedance in Biomedical Instrumentations  [in Japanese]

Abstract

The author proposes a measuring method of complex bioimpedance in real time by using a potentiostat circuit and LabVIEW programming tools. In the system, 4-electrode method is applied on the dc-coupled potentiostat. Complex impedance is calculated from the frequency response function in LabVIEW. The resolutions of the resistive and reactive components are about 0.005% respectively. As a preliminary experiment, the complex impedance on a middle finger at 1kHz is measured with sampling time of 10ms. Pulse waves of resistive components which are synchronizing with ECG are clearly observed and very small reactive components.
