Hardly any other principle of electromechanical transduction has contributed more to the advance of consumer mechatronic products than
piezoelectricity
. The most prominent instantiations of so-called
unconventional
transduction principles, piezo elements are
solid-state transducers
, and can be incorporated directly into mechanical components without complicated structural requirements (forming
smart structures
); generate high to very high forces in a minimal volume; have high dynamic response; and can even be operated without auxiliary energy in some applications (oscillation damping,
shunting
) or employed in the generation of electricity (
energy harvesting
).
