Homogeneity Characterization of Textile-Integrated Wearable Sensors based on Impedance Spectroscopy

open access: yesSensors, 2022
One of the main challenges during the integration of a carbon/polymer-based nanocomposite sensor on textile substrates is the fabrication of a homogeneous surface of the nanocomposite-based thin films, which play a major role in the reproducibility of ...

Mangrove bark tannins as a Zn–P coating sealant for mild steel corrosion protection in 3.5% NaCl solution

open access: yesMaterials Research Express, 2020
In this work, mangrove bark tannins have been studied as a sealant after Zn–P of mild steel. The efficiency of the sealant against the corrosion was tested by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation (PD) in 3.5% NaCl

A full capacitive picture of the constant phase element: Estimations from impedance spectroscopy, distribution of relaxation times and fractional calculus

open access: yesElectrochemistry Communications
Impedance spectroscopy (IS) is classically used to study the dynamical properties of electrochemical systems but now is also often accompanied by chrono-based methods and the emerging analysis tool of fractional calculus to provide timescale information.

Fractional calculus model of electrical impedance applied to human skin. [PDF]

open access: yesPLoS ONE, 2013
Fractional calculus is a mathematical approach dealing with derivatives and integrals of arbitrary and complex orders. Therefore, it adds a new dimension to understand and describe basic nature and behavior of complex systems in an improved way.
