Electrical Impedance Spectroscopy and Roots

2011
This chapter reviews studies dealing with the characterization of the plant root system by the electrical impedance method, i.e., with resistance and capacitance at a single frequency or at multifrequencies, according to the approach used in electrical impedance spectroscopy (EIS). Several studies have shown a correlation between electrical capacitance

Understanding the validity of impedance and modulus spectroscopy on exploring electrical heterogeneity in dielectric ceramics

Journal of Applied Physics, 2019
Combined modulus and impedance spectra are widely employed to explore electrical inhomogeneity and carriers' behaviors in dielectric ceramics based on equivalent circuit.

Electrical Impedance imaging of the Thorax

Journal of Microwave Power, 1983
In this paper, we propose to develop a new imaging technology, computerized impedance tomography (CIT) for imaging the thorax. Our study involves reconstructing images of thoracic transverse plane impedance distributions noninvasively and nondestructively and exploring the potential of CIT.

Electrical Impedance Plethysmography

Archives of Internal Medicine, 1962
Plethysmography has proven to be a valuable method for studying the dynamics of peripheral vascular beds in normal and pathologic states and for evaluating the effects of drugs upon these beds. Refinements of the method, such as graded outflow hindrance and stopflow studies, have permitted separation of the pulsatile arterial inflow and venous runoff ...

Electrical Impedance Spectroscopy

2018
This chapter gives some background on impedance spectroscopy and tissue impedance but also about the instrumentation used for measuring transfer impedance of a biological material under study. The instrumentation concerned here is the current source for applying a current to tissue and the differential amplifier for measuring the resultant voltage.
