Estimating Cole-Impedance Parameters from Limited Frequency-Band Impedance Measurements

Particle-swarm optimization is applied to estimate the parameters of 4 different Cole-impedance models using impedance measurements limited to frequencies within 1 kHz to 1 MHz, representative of typical ranges for bioimpedance applications. The accuracy of extracted parameters are compared for cases with $N$ = 201, 25, and 5 datapoints collected using a Keysight E4990A impedance analyzer and $N$ ...
