Piezoelectric transducers assessed by the pencil lead break for impedance-based structural health monitoring
(Ieee-inst Electrical Electronics Engineers Inc, 2015-02-01)
The pencil lead break (PLB) is a well-known method for characterizing acoustic emission sensors. In this paper, we analyze the effectiveness of this method in characterizing piezoelectric transducers for structural health ...
Modeling of functionally graded piezoelectric ultrasonic transducers
(ELSEVIER SCIENCE BV, 2009)
The application of functionally graded material (FGM) concept to piezoelectric transducers allows the design of composite transducers without interfaces, due to the continuous change of property values. Thus, large ...
Development of a piezoelectric transducer coupling system for structural health monitoring applications
(2019-10-01)
Piezoelectric transducers have been widely used in structural health monitoring (SHM) frameworks. Recently, preliminary applications of these devices have emerged in the field of ultrasonic waves based on transmitter/receiver ...
Evaluation of the piezoelectric behaviour produced by a thick-film transducer using digital speckle pattern interferometry
(Elsevier, 2011-02)
This paper presents an interferometric measurement of the out-of-plane deflections produced by a piezoelectric transducer, manufactured by thick-film deposition of a ceramic paste over an alumina substrate, when is subjected ...
Sensitivity Enhancement of Piezoelectric Transducers for Impedance-Based Damage Detection via a Negative Capacitance Interface
(2020-12-01)
Piezoelectric transducers are used in many applications due to electromechanical coupling, which allows mechanical and electrical quantities to be related. This principle is used in the development of structural damage ...
Toward Optimal Design of Piezoelectric Transducers Based on Multifunctional and Smoothly Graded Hybrid Material Systems
(SAGE PUBLICATIONS LTD, 2009)
This work explores the design of piezoelectric transducers based on functional material gradation, here named functionally graded piezoelectric transducer (FGPT). Depending on the applications, FGPTs must achieve several ...
PTCa/PEEK composite acoustic emission sensors
(2006-10-01)
Composites made of Calcium-modified lead titanate (PTCa) and poly (ether-etherketone) (PEEK) high performance polymer matrix were prepared in the film form using a hot press. The ceramic volume fraction reaches up to 60 ...
