Estimating electrical properties and the thickness of skin with electrical impedance spectroscopy: Mathematical analysis and measurements

open access: yesJournal of Electrical Bioimpedance, 2012
Electrical impedance spectroscopy (EIS) allows for the study and characterization of tissue alterations and properties associated with the skin. Here, the potential application of EIS to estimate the thickness of the stratum corneum is explored in the ...

Measuring individual overpotentials in an operating solid-oxide electrochemical cell

open access: yes, 2010
We use photo-electrons as a non-contact probe to measure local electrical potentials in a solid-oxide electrochemical cell. We characterize the cell in operando at near-ambient pressure using spatially-resolved X-ray photoemission spectroscopy.

Non-destructive Analysis of Pamelo Citrus Fruit Maturity with Impedance Spectroscopy Method

open access: yesAndalasian International Journal of Applied Science, Engineering, and Technology
Citrus fruit is a fruit that is favored by the public. The quality of the fruit from the garden to the consumer goes through a long process. Generally, the quality of the fruit is evaluated by a visual judgment ratio that can be wrong.

Electrochemical impedance spectroscopy to study physiological changes affecting the red blood cell after invasion by malaria parasites [PDF]

open access: yes, 2009
The malaria parasite, Plasmodium falciparum, invades human erythrocytes and induces dramatic changes in the host cell. The idea of this work was to use RBC modified electrode to perform electrochemical impedance spectroscopy (EIS) with the aim of ...
