试验设计

In this work, the performance of six-needle steel electrodes and four-needle graphite electrodes in detecting bio-impedance was compared. Also, coefficients of variability were applied to assess the stability of the system. Experiment showed that the coefficient of variation of the system was less than 6% if the frequency was above 1 kHz. Intra class correlation procedures were applied to assess the reliability of the system due to temperature variability. Values of Ri, Re, C in the system model were reliable with intra class correlations of more than 65%.
