Statistical study In general 3 experiments were taken into account in order to calculate dispersion parameters as standard deviation and variation coefficient (RSD). The last column in Table S1 shows the percentage variation of the interfacial impedance modulus when recognition reaction was taking place. Indeed the interfacial impedance variation on a surface coated with BSA is in a linear rela...

The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...

Regional cerebral blood flow and blood volume changes that occur during human brain activity will change the local impedance of that cortical area, as blood has a lower impedance than that of brain. Theoretically, such impedance changes could be measured from scalp electrodes and reconstructed into images of the internal impedance of the head. Electrical Impedance Tomography (EIT) is a newly de...

Abstract We study the relationship between surface mechanical load represented by distributed acoustic impedance and current density distribution in a shear mode piezoelectric plate wave resonator. A theoretical analysis based on theory of piezoelectricity trigonometric series is performed. In specific basic case when due to local mass layer, numerical results show that concentrates under layer...

For electronic products, interconnect failures may occur due to mechanisms such as fatigue, creep, corrosion, and mechanical over-stress. Regardless of the failure mechanism, interconnect degradation often starts at a surface and propagates inward. DC resistance, which has been used by the electronics industry to monitor the reliability of board level interconnects, does not offer an adequate m...

The response mechanism of the iron(III) chalcogenide glass membrane ion-selective electrode (ISE) in saline media has been studied using electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). EIS equivalent circuits and XPS surface compositions for the FeIII ISE are consistent with the presence of two surface films probably comprising a outer surface layer (OSL...

It is shown that a surface wave will be generated by a horizontal.slot situated above a corrugated or dielectric-coated guiding surface. A physical interpretation of the analysis is suggested which explains the mechanism of launching in terms of a resonance phenomenon allied to that which arises when a piston attenuator is terminated by a reactance equal and opposite to its own (reactive) chara...

This paper presents an overview and recent advances in impedance-based structural health monitoring. The basic principle behind this technique is to apply high-frequency structural excitations (typically greater than 30kHz) through surface-bonded piezoelectric transducers, and measure the impedance of structures by monitoring the current and voltage applied to the piezoelectric transducers.
