“…Although this model has been successfully used in many cases, 17 a large number of applications requires models with additional degrees of freedom that are able to accurately fit the measured impedance magnitude and phase responses over a specific frequency range of interest. Therefore, the well‐known Cole–Cole (C‐C), Cole–Davidson (C‐D), and the more general Havriliak–Negami (H‐N) models are widely used particularly in bio‐impedance analysis 18‐20 . The three‐parameter H‐N model is given by

H_{H N} false(s false) = \frac{1}{{([], 1 + {((), τ s)}^{α})}^{β}},

where

α

and β are fractional orders (dispersion coefficients) and τ is a characteristic time‐constant.…”

Summary Double‐exponent fractional‐order impedance functions are important for modeling a wide range of biochemical materials and biological tissues. Through appropriate selection of the two exponents (fractional orders), the well‐known Havriliak–Negami, Cole–Cole, Cole–Davidson, and Debye relaxation models can be obtained as special cases. Here we show that an integer‐order Padé‐based approximation of the Havriliak–Negami function is possible to obtain and can be realized using appropriately configured Cauer/Foster resistor‐capacitor (RC) networks. Two application examples are subsequently examined: the emulation of the capacitive behavior in a polycrystalline solid electrolyte and the emulation of the impedance of four “fractal” vegetable types.

The bio-impedance of a plant varies according to the tissue composition, type, and sample status whether it is a fresh sample or a physical heat/freeze treatment was applied to it [9].…”

Recent works show that the plants can exhibit nonlinear memristive behavior when excited with low-frequency signals. However, in the literature, only linear bio-impedance models are extensively considered to model the electrical properties of biological tissues without acknowledging the nonlinear behavior. In this paper, we show with experiments, for the first time, the pinched hysteresis behavior in seven fruits and vegetables including tomato, orange, lemon, aubergine, and kiwi which exhibit single pinchoff point, and others such as carrot and cucumber exhibit double pinch-off points (i.e., three lobes). We also proposed a memristive fractional-order bio-impedance model by extending the Hayden bio-impedance model. The proposed model is used to fit the measurements of the seven fruits and vegetables showing very good matching.

“…Tissue bioimpedance is related to the type of tissue, intra/extra cellular fluids, and overall tissue structure [3] . Bioimpedance measurements have been utilized for applications including: body composition determination [4] , [5] , clinical tomography [6] , cardiography [7] , respiratory monitoring [8] , and even food monitoring applications [9] . Bioimpedance is also currently being investigated as a noninvasive technique to characterize skeletal muscle tissue with a particular focus on assessing neuromuscular disorders [10] , [11] , [2] .…”
