Electrical impedance of the pituitary gland [PDF]
Journal of Neurosurgery, 1970 ✓ Experimental and clinical measurements of electrical impedance revealed a significant well-delineated difference between the pars distalis and the pars nervosa, providing an accurate and easy means of identifying the tissue interface between these two elements of the pituitary gland.

Definition of Impedance and Impedance of Electrical Circuits [PDF]
, 2013 To understand the impedance of electrochemical objects, it is necessary to understand the behavior of simple electrical circuits, first in steady state, then in transient conditions. Such circuits contain simple linear electrical elements: resistance, capacitance, and inductance. Then the concept of electrical impedance will be introduced.

Electric impedance of neuroglia in vitro
Experimental Neurology, 1965Abstract Impedance measurements were carried out on neuroglia cells from tissue culture and newborn animals as studied in vitro . Approximately 240 cells were estimated to be present in the material studied. Membrane resistivity could be measured only at a-c frequencies below 200 cycle/sec. Both electric shocks and KCl applied to the tissue produced

The concept of surface impedanceZ E of an electric ac-fieldE ⊥ perpendicular to metal surfaces is developed and then applied to clean and oxide coated metals. Whereas clean metals show values forZ E which are not detectable, yet; oxide coated metals show very much enhancedZ

Multifrequency electrical impedance tomography
Clinical Physics and Physiological Measurement, 1992Multifrequency tomography may be conveniently achieved by sequentially sweeping the probing drive current and measuring the resultant voltages at each frequency. If events change during measurement comparisons between frequencies cannot be made. Mixing several frequency components may decrease acquisition time but increase the complexity of the ...

A phantom for electrical impedance tomography [PDF]
Clinical Physics and Physiological Measurement, 1988 A method has been developed for constructing phantoms for electrical impedance tomography (EIT). A mesh of resistors is soldered to pins in a matrix board and forms a physical realisation of a finite element numerical model. To simulate different body tissues, changes in the apparent electrical conductivity and permittivity can be introduced at a ...

An electrical impedance tomography microscope
Physiological Measurement, 1996A circular array of 16 electrodes has been constructed for use as an electrical impedance tomography (EIT) microscope. The electrodes were made from 60 microns diameter gold wires anchored to a printed circuit board. The internal diameter of the array was 0.9 mm giving a theoretical spatial resolution of about 100 microns.
