Extracting Optimized Bio-Impedance Model Parameters Using Different Topologies of Oscillators

This paper demonstrates the possibility of extracting the single-dispersion and double-dispersion Cole-bio-impedance model parameters using oscillators (sinusoidal or relaxation). The method is based on replacing selected components in the oscillator structure with the biological sample under test and then using the Flower Pollination optimization Algorithm (FPA) to solve a set of nonlinear equations in order to extract the unknown model parameters. Minimum component sinusoidal oscillators and relaxation oscillators are used in this work and experimental results on three samples of four different fruits (Apple, Guava, Eggplant, and Tomato) are reported and compared with results obtained from a precise research-grade BioLogic SP150 electrochemical station.
