Abstract :
Impedance techniques have been widely applied to the biomedical engineering field. In order to obtain definite results from bioimpedance, multi-channel measurement is effective. A linearity of biological tissue and fundamental technical parameters for the instrument must be confirmed. In this study, the fundamental conditions have been investigated for multi-channel bioimpedance measurement and the condition of measurement for biological tissue has been confirmed. The differences of every measurement frequency should be appropriate to 1 kHz and it has been shown that the linearity of biological tissue is maintained. Based on these results, a two-channel bioimpedance measurement instrument has been constructed
