A New Impedance Measurement System for PZT-Based Structural Health Monitoring
(Institute of Electrical and Electronics Engineers (IEEE), 2009-10-01)
Recent research has shown that electromechanical (E/M) impedance-based techniques are an efficient strategy for damage sensing in the context of structural health monitoring (SHM). The basic principle is to excite the lead ...
Using the electrochemical impedance spectroscopy to characterize carbon steel in biodiesel medium
(2012-12-01)
Electrochemical impedance spectroscopy measurements using two carbon steel electrodes in soybean biodiesel medium, produced by methylic route, were performed in an electrochemical cell that allows positioning the two ...
On the concept of electrical impedance for an electrolytic cell
(TAYLOR & FRANCIS LTD, 2008)
The analysis of the electrical impedance of an electrolytic cell in the shape of a slab is performed. We have solved, numerically, the differential equations governing the phenomenon of the redistribution of the ions in ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(2001-11-01)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
