Influence of normal and radial contributions of local current density on local electrochemical impedance spectroscopy
(Pergamon-Elsevier Science LtdOxford, 2012)
A new tri-electrode probe is presented and applied to local electrochemical impedance spectroscopy (LEIS) measurements. As opposed to two-probe systems, the three-probe one allows measurement not only of normal, but also ...
Impedance function calculation for the study of waves in locally periodic arrangements
(IOP Publishing, 2015-08)
In this paper, we study theoretically the propagation of waves in locally periodic systems. To this end, we employ a simple method based on the impedance function which is similar to the one used in the transmission line ...

Assay based on electrical impedance spectroscopy to discriminate between normal and cancerous mammalian cells
(American Physical Society, 2018-03-19)
In this work we present an assay to discriminate between normal and cancerous cells. The method is based on the measurement of electrical impedance spectra of in vitro cell cultures. We developed a protocol consisting on ...

On the dual side of operational dynamics: A formulation, applications, and implications of the impedance model
This paper studies the operational dynamics of a structure in steady state under a given source. It is based on the duality of operational structural dynamics, which states that the structure in operation can be viewed ...
Análise estatística de impedância da pele
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciências BiológicasBiodiversidade; Biologia Estrutural e Funcional., 2011-03-29)
In this work we analyze the skin bioimpedance statistical distribution. We focus on the study of two distinct samples: the statistics of impedance of several points in the skin of a single individual and the statistics ...
Structural FRF acquisition via electric impedance measurement applied to damage location
(Soc Experimental Mechanics Inc, 2000-01-01)
Continuing development of new materials makes systems lighter and stronger permitting more complex systems to provide more functionality and flexibility that demands a more effective evaluation of their structural health. ...
