ELECTROMECHANICAL DELAY - AN EXPERIMENTAL ARTIFACT
(Butterworth-heinemann LtdOxfordInglaterra, 1992)
Nanoscale electromechanical properties of CaCu3Ti4O12 ceramics
(American Institute of Physics (AIP), 2011-09-01)
Piezoresponse Force Microscopy (PFM) is used to characterize the nanoscale electromechanical properties of centrosymmetric CaCu3Ti4O12 ceramics with giant dielectric constant. Clear PFM contrast both in vertical (out-of-plane) ...
Experimental study of the variations in the electromechanical properties of piezoelectric energy harvesters and their impact on the frequency response function
(Academic Press, 2019)
This work presents a comprehensive study of the uncertainties involved in the FrequencyResponse Function (FRF) of Piezoelectric Energy Harvesters (PEHs) based on experimentalresults. A proper experimental setup is designed ...
Structure, microstructure, ferroelectric/electromechanical properties and retention characteristics of [Bi1-x Nb (x) ]FeO3 thin films
In this work, we report the structure, microstructure, ferroelectric/electromechanical properties, and retention characteristics of [Bi1-x Nb (x) ]FeO3 (BNFO) thin films [x=0,0.025,0.05, and 0.1] prepared by the polymeric ...
Design, construction, and performance of a device for directional recrystallization of metallic alloys
(American Institute of Physics, 2017-02)
A device was designed to apply the directional recrystallization method to Fe-based alloys in order to obtain bamboo-like microstructures. This microstructure is suitable for improving creep properties and resistance to ...
Piezoelectricity is a phenomenon in which certain crystalline substances develop an electric field when subjected to pressure force, or conversely, exhibit a mechanical deformation when subjected to an electric field. This ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
Electromechanical characterization of piezoelectric polymer thin films in a broad frequency range
Piezoelectric materials are usually characterized using resonant methods. However, piezoelectric polymers are used in broadband devices, thus requiring characterization over a wide range of frequencies. In this work, we ...
Electromechanical impedance (EMI) technique as alternative to monitor workpiece surface damages after the grinding operation
Electromechanical impedance (EMI) technique has been employed in detection of structural failure in civil and mechanical structures because of its non-destructive property and easy implementation of small and inexpensive ...
