“…Electrical impedance spectroscopy determines the impedance of the soil–plant continuum across a range of frequencies (hertz to megahertz). This method has been used in many studies in plant science and medicine (Bera, Bera, et al., 2016; Bera, Nagaraju, & Lubineau, 2016; Coster, Chilcott, & Coster, 1996; Hayden, Moyse, Calder, Crawford, & Fensom, 1969; Inaba, Manabe, Tsuji, & Lwamuto, 1995; Klauke et al., 2005; Lin, Chen, & Chen, 2012; Macdonald, 1992; Shrivastava, Barde, Mishra, & Phadke, 2014a, 2014b). For root studies, EIS has been used to assess the morphological and physiological properties of roots such as root growth (Ozier‐Lafontaine & Bajazet, 2005; Repo, Laukkanen, & Silvennoinen, 2005), estimation of root system size (Cao, Repo, Silvennoinen, Lehto, & Pelkonen, 2011), and mycorrhizal colonization of roots (Cseresnyés, Takács, Végh, Anton, & Rajkai, 2013; Repo, Korhonen, Laukkanen, Lehto, & Silvennoinen, 2014; Repo, Korhonen, Lehto, & Silvennoinen, 2016), as summarized in Table 4.…”

Thorough knowledge of root system functioning is essential to understand the feedback loops between plants, soil, and climate. In situ characterization of root systems is challenging due to the inaccessibility of roots and the complexity of root zone processes. Electrical methods have been proposed to overcome these difficulties. Electrical conduction and polarization occur in and around roots, but the mechanisms are not yet fully understood. We review the potential and limitations of low‐frequency electrical techniques for root zone investigation, discuss the mechanisms behind electrical conduction and polarization in the soil–root continuum, and address knowledge gaps. A range of electrical methods for root investigation is available. Reported methods using current injection in the plant stem to assess the extension of the root system lack robustness. Multi‐electrode measurements are increasingly used to quantify root zone processes through soil moisture changes. They often neglect the influence of root biomass on the electrical signal, probably because it is yet to be well understood. Recent research highlights the potential of frequency‐dependent impedance measurements. These methods target both surface and volumetric properties by activating and quantifying polarization mechanisms occurring at the root segment and cell scale at specific frequencies. The spectroscopic approach opens up a range of applications. Nevertheless, understanding electrical signatures at the field scale requires significant understanding of small‐scale polarization and conduction mechanisms. Improved mechanistic soil–root electrical models, validated with small‐scale electrical measurements on root systems, are necessary to make further progress in ramping up the precision and accuracy of multi‐electrode tomographic techniques for root zone investigation.

“…It is a common fact that grain size is a very important parameter getting high dielectric constant. It is reported that samples have fine grain size consists of higher internal stress than the coarsely grained samples [22]. Density is also an important parameter in the process of polarization phenomenon.…”

Polycrystalline xBa 0.95 Sr 0.05 TiO 3 -(1 − x)BiFe 0.90 Gd 0.10 O 3 ceramics were prepared by standard solid state reaction technique using the solid solution of BaCO 3 , SrCO 3 , TiO 2 , Bi 2 O 3 , Fe 2 O 3 and Gd 2 O 3 . The compound is a BiFeO 3 based multiferroic material which contains both magnetic and electric properties. The synthesized ceramics noticed better properties than xBaTiO 3 -(1 − x)BiFeO 3 because of adding rare earth element Gd which have higher magnetic moment than Fe. The prepared samples were sintered at 900˚C, 950˚C and 1000˚C for 1 h. The effect of sintering temperature on density of the compound, complex initial permeability, dielectric properties and complex impedance analysis was reported in this article. Density of the ceramics was found to be enhanced with the rise in sintering temperature which implied porosity of the compound decreased when sintering temperature was increased. Enhanced complex initial permeability was noticed for the samples up to 950˚C and this might be attributed to reducing the motion of domain wall when the ceramics were sintered above 950˚C. Value of dielectric constant increased whereas dielectric loss decreased and these modifications might be expected because of changing density and grain size due to the variation of sintering temperature. Grain resistance (resistance due to grains) was determined from complex impedance analysis and it reduced with the rise in sintering temperature. The studied multiferroic material exhibited weak ferromagnetism but is an alternative product of environmental hazard lead (Pb) based multiferroic material and it is expected to be environment friendly.

“…The results show that the dielectric constant of tissues, cells and animal bones is very high at low frequencies and decreases with increasing frequency. Studies of the frequency dependence of the dielectric constant of objects of biological origin can determine such important physical constants as coefficients of absorption, reflection, refraction, and establish the scope of their practical application [10]- [12]. New materials obtained based on polymers with fillers of biological origin can certainly open up new scientific-practical possibilities.…”

This paper presents the results of studying the frequency dependence of permittivity and dielectric loss of fishbone (Fb) Kutum and polyethylene composites filled with nanoparticles fishbone Kutum and the influence of aluminum(Al) nanoparticles with dimensions 80-nm on the dielectric properties of polymer composites. Studies were carried out at the frequency range of 0-1 MHz. It was found that the variation of the volume of filler content of fishbone and aluminum nanoparticles might be prepared composite materials with the required dielectric parameters.
