This paper reviews the evolution of focused ultrasonic transducers of various kinds for fluid
atomization and vaporization. Ultrasonic transducers used for atomization purposes in …

We analyze the first-order gradient effects in micro piezoelectric-bimorph circular plate
(PBCP) power harvesters by including the first-order gradient terms in the energy density …

This paper presents a new approach to amplify the acoustic field generated by a uniform
thickness piezoelectric cylindrical shell by introducing a stepped thickness variation at …

In this work, a new design method is proposed to intensify the focused acoustic field
generated inside a circular cylindrical piezoelectric transducer. The proposed design …

A circular thin plate is proposed for vibration attenuation, which is attached alternately by
annular piezoelectric unimorphs with resonant shunt circuits. Two kinds of equal frequency …

Computer modeling and experimental tests were used to study the influence of piezoelectric
material nature and geometry of cylindrical hydro-acoustic transducers and piezobimorphs …
