Impedance and Electric Modulus Studies on Polyaniline/Nickel Ferrite (PANI/NiFe2O4) Composites

Electric Impedance

Electrical impedance tomogram of the mammary gland (EIM). Seven planes of scanning. In the sixth and the seventh scans, a retromammary tissue is visualized. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasoundbased medical imaging technique. In this study, a new platform based on electric cell-substrate impedance sensing ...

Dielectric Permittivity and Electric Modulus in Bi2Ti4O11

Electric Impedance of Arbacia Eggs

The alternating current resistance and capacity of suspensions of unfertilized and fertilized eggs of Arbacia punctulata have been measured at frequencies from 10(3) to 1.64 x 10(7) cycles per second. The unfertilized egg has a static plasma membrane capacity of 0.73 microf./cm.(2) which is practically independent of frequency. The fertilized egg has a static membrane capacity of 3.1 microf./cm...

Electric Impedance of Hipponoë Eggs

Alternating current resistance and capacity measurements have been made from 1.08 10(3) to 2.32 10(6) cycles per second on suspensions of unfertilized, fertilized, and swollen unfertilized eggs of the echinoderm Hipponoë esculenta. A simple method has been developed for measuring the volume concentration of eggs in a suspension. The membrane of the unfertilized egg is practically non-conducting...

Limitations of electric impedance plethysmography.

Klectrie impedance plethysmography has been offered as a substitute for mechanical plethysmography and would be particularly suitable for regions in which the mechanical method cannot be applied. A comparative investigation of mechanical and impedance plethysmograms, taken simultaneously from a finger or a forearm, revealed that, while the normal pulsations were reproduced reasonably well, elec...
