Aloe Vera Tissue Modeling and Parameter Identification Using Meta-heuristic Optimization Algorithm

The agricultural industry's use of non-invasive bioimpedance monitoring methods is expanding quickly. These measured impedance fluctuations reflect imperceptible biophysical and biochemical changes in living and non-living tissues. Bioimpedance circuit modeling is a valuable method for fitting the measured impedance in biology and medicine. A study on two samples of Aloe Vera leaves is conducted to identify the best model representing Aloe Vera leaves, and two different interelectrode spacing distances are used to measure each sample. An electrochemical station (SP150) is used to detect bio-impedance at frequencies between 80 Hz and 200 kHz. The effectiveness of the employed models is evaluated by fitting them to the measured data. Among all models used, the medical plant stem and simplified plant stem models show the best results for all inter-electrode spacing distances. © 2023 IEEE.
