  text: 'This article is dedicated to piezoelectric ultrasonic power transducers that
    differ to well known medical ultrasonic diagnostic apparatus or non destructive
    testing devices by the level of power in use; typically several tens of up to
    more than thousand watts are used in a multitude of different applications. After
    a short introduction including historical development, the first focus is on theoretical
    background of the operating principle, design and mechanical modeling. As piezoelectric
    elements transform electrical to mechanical energy and vice versa, equivalent
    circuit modeling is also described. After that, sample applications are delineated
    by the matter wherein ultrasound generates unique effects: incredible high pressure
    level as well in air as in water, micro-bubbles generating temperature peaks for
    very short time instances in fluids, acoustoplastic effect, enhancement of diffusion
    and recrystallization in solids, friction manipulation, incremental deformation
    and micro-cracking of surfaces, or even generation of macroscopic movements in
    motors. At the end, some future directions ranging from novel modeling approaches
    to advanced control and new materials are addressed.'
