In this paper, a continuum electromechanical model of a Langevin ultrasonic transducer is
developed considering acoustic losses of contact surfaces. The calculated energy losses …

One-dimensional models of piezoelectric transducers allow the rapid prediction of
performance as well as assisting an understanding of transducer behaviour. This chapter …

Abstract A three-dimensional (3D) model of a high-power ultrasonic, composite,
unidirectional transducer is proposed in this paper. The proposed 3D Matlab/Simulink model …

Broadband ultrasonic transducers have many advantages, such as, short time response,
high resolution in axis, wide band of launching and receiving waves. In this paper, the KLM …

In recent years, MEMS (micro-electrical mechanical systems) microphones have been used
as low-cost alternatives to more costly phased arrays condenser microphones. More study of …

This paper describes the construction of a new generation of flexible ultrasonic transducers.
The device consists of an array of piezoceramic platelet devices of high aspect ratio …

One-dimensional (1D) model of piezoelectric elements enable fast prediction of
performance, as well as a good insight into the behaviour of piezoelectric elements and the …

An electromechanical coupling model of a bending vibration type piezoelectric ultrasonic
transducer is proposed. The transducer is a Langevin type transducer which is composed of …

The study of the acoustic field generated by an ultrasonic transducer is fundamental to its
construction and characterization, because it defines how it will behave before being built. It …
