Bioelectrical impedance analysis and bioelectrical impedance spectroscopy (BIA/BIS) of tissues reveal important information on molecular composition and physical structure that is useful in diagnostics and prognostics. The heterogeneity in structural elements of cells, tissues, organs, and the whole human body, the variability in molecular composition arising from the dynamics of biochemical reactions, and the contributions of inherently electroresponsive components, such as ions, proteins, and polarized membranes, have rendered bioimpedance challenging to interpret but also a powerful evaluation and monitoring technique in biomedicine. BIA/BIS has thus become the basis for a wide range of diagnostic and monitoring systems such as plethysmography and tomography. The use of BIA/BIS arises from (i) being a noninvasive and safe measurement modality, (ii) its ease of miniaturization, and (iii) multiple technological formats for its biomedical implementation. Considering the dependency of the absolute and relative values of impedance on frequency, and the uniqueness of the origins of the α-, β-, δ-, and γ-dispersions, this targeted review discusses biological events and underlying principles that are employed to analyze the impedance data based on the frequency range. The emergence of BIA/BIS in wearable devices and its relevance to the Internet of Medical Things (IoMT) are introduced and discussed.

“…The impedance of biological tissues changes with the stimulation frequency. The effect of equivalent internal and exterior resistance, as well as membrane capacitance, on the impedance spectroscopy of biological tissue microstructures is investigated using an impedance model [31]. The real part of the impedance spectroscopy decreases monotonically and tends to stabilize as frequency increases and impedance decreases to a certain point, with extreme points appearing in the imaginary part [5].…”

Electrical impedance tomography can reconstruct the complex conductivity distribution by injecting a current or voltage at a specific frequency into the target domain. The complex conductivity spectroscopy of numerous biological tissues is frequency-dependent. A suitable excitation frequency is vital to high-quality imaging over a wide frequency range. This paper investigates the relationship between the parameters of the biological tissue impedance model and the impedance spectroscopy. A frequency selection method based on the impedance spectroscopy is proposed, in which the impedance spectroscopy on a specific electrode at the domain boundary to be measured is first scanned. In TD-EIT, the difference between the target’s impedance spectroscopy and the null field is calculated, and the frequency corresponding to its extreme value is used as the excitation signal for TD-EIT. The excitation frequency in FD-EIT is the frequency corresponding to the extreme point in the target impedance spectroscopy, and we have also used this method to image the interior of the maize ear. This study provides a quick and efficient method for determining the excitation frequency for EIT, allowing researchers to find the best excitation frequency for high-quality imaging during actual measurements.

“…Electrochemical impedance spectroscopy (EIS) is a method for analyzing the electrical properties of plant organisms, such as vegetables and fruits. It has been widely studied because it provides useful electrical information about the organisms and the dielectric materials [1][2][3][4][5][6][7][8][9][10][11][12]. A common research method is to measure the impedance of a sample using an LCR meter or an impedance analyzer, display the measurement results on Nyquist plots (Cole-Cole plots), and analyze the frequency characteristics of the dielectric constant and equivalent circuit.…”

We measured the S-parameters of six different types of liquid samples, such as aqueous alcohol solutions, NaCl ionic solutions, alcoholic beverages, and fruit juices in the 1 to 100 MHz frequency range, and calculated their impedance and admittance. Equivalent circuits of the liquid samples were synthesized by curve fitting on a Smith chart and Cartesian coordinates. The relationship between the impedance, admittance, and circuit element values of the synthesized equivalent circuit and the ethanol C2H5OH, polar water molecule H2O, and cation (K+ ion) that constitute the liquid sample was analyzed. Distilled alcoholic beverages showed a high impedance, but the impedance decreased after aging. Non-distilled alcoholic beverages showed a significant decrease in impedance due to cation (K+ ion). The impedance of the dehydrated reduced concentrated beverage increased significantly due to the reduction of cation (K+ ion).
