Electrical impedance tomography (EIT) is a recently developed medical imaging method which has practical advantages for imaging brain function as it is inexpensive, rapid and portable. Its principal use in validated human studies to date has been to image changes in impedance at a single excitation frequency over time, but there are potential applications where it is desirable to obtain images ...
Non-invasive glucose monitoring is crucial for effective diabetes mellitus treatment while a sound correlation of a non-invasive parameter to glucose level variation is quite challenging. This paper presents characterization of glucose concentrations using Electrical Impedance Spectroscopy (EIS) in three different solutions: 1) 0.9% NaCl, 2) Saline (NaCl 1.3gm, KCl 0.75gm, Na3C6H5O7 1.45gm, D-g...
Information on plant roots is increasingly needed for understanding and managing plants under various environmental conditions, including climate change. Several methods have been developed to study fine roots but they are either destructive or cumbersome, or may not be suitable for studies of fine root functionality. Electrical impedance, resistance, and capacitance have been proposed as possi...
Electrochemical performance of binary and ternary oxides composed of Ni, Co and Cu produced over a 3-dimensional substrate of vertically aligned carbon nano-tubes (VACNT) as electrodes for aqueous energy sources, is reported and compared in this paper. VACNTs were fabricated inside a DC-plasma enhanced chemical vapor deposition chamber and composite materials fabricated by thermal decomp...
Electrical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measure properties of the electrode-tissue interface without additional invasive procedures, and can be used to monitor electrode performance over the long term. EIS measures electrical impedance at multiple frequencies, and increases in impedance indicate increased glial scar formation around the device, while cyclic voltamme...
Membrane parameters characteristic for the study of electrolyte solutions across microporous membranes such as salt permeability, ion transport numbers and membrane electrical resistance have been determined for a ceramic microfiltration membrane by measuring salt diffusion, membrane potential and impedance spectroscopy (IS), respectively. In order to see the effect of ion charge and concentrat...
Electrical transport properties of CoMn0.2−xGaxFe1.8O4 ferrites using complex impedance spectroscopy
Breast Cancer is among the top five causes of cancer death and topmost cause among women worldwide. The early diagnosis through simple, non-invasive and inexpensive screening can provide great deal of aid especially for the poor people of Bangladesh. Making diagnostics measurement available to the widely geographically spread population in developing countries is a challenge which is unlikely t...
