Health Monitoring of Single-Element Piezoelectric Transducer Using Its Electromechanical Admittance
W. Ding, M. Bavencoffe, M. Lethiecq
The transducer is an essential part of all ultrasonic systems used for applications such as medical diagnostics, therapy, nondestructive evaluation, and cleaning because its health condition is vital to their proper operation. Defects within the active element, backing or other constitutive elements, and loss of adhesion between layers can significantly weaken the performance of ...

A New Prospect in Road Traffic Energy Harvesting Using Lead-Free Piezoceramics
Manuel Vázquez-Rodríguez, Francisco J. Jiménez, Lorena Pardo, Pilar Ochoa, Amador M. González and José de Frutos.
In this paper, a new prospect using lead-free piezoelectric ceramics is presented in order to determine their behavior in piezoelectric-based road traffic energy harvesting applications. This paper will describe the low-cost and fully programmable novel test bench developed. The test bench includes a traffic simulator and acquires the electrical signals of the piezoelectric material...
