Piezomechanics as a subsystem of mechatronics: present state of the art, problems, future developments

The concept of piezomechanics (piezoelectricity+mechanics+a control system) describing a complex interaction of dynamic effects and precision engineered devices is discussed. Piezomechanics is considered as part of the more broad philosophy of mechatronic devices. The object and structure of piezomechanics are presented as well as the primary linear and nonlinear effects, on which energy, motion and signal transformation processes are based. Novel applications are proposed to illustrate the potential benefits, including adaptive mechanical systems in addition to multifunctional and intelligent devices.
