چکیده
The present paper gives an overview on actual developments of the application of piezoelectric components in transportation industry. During the last decades, piezoelectric materials made huge progress in entering commercial mass markets throughout all branches, where piezoelectrics are used as the basis materials for actuators as well as sensors. Especially in transportation industry, they found numerous fields of applications. The development of piezoelectric actuators for fuel injection systems is a popular application of the near past, active noise and vibration reduction is a current activity, and the use of piezoelectric materials for energy harvesting in vibrating structures is one possible future trend. Recent developments in ceramic processing and possibilities in tailoring of special properties will be shown as well as latest developments in manufacturing of piezoelectric actuator and sensor components. Another part of the paper is the aspect of reliability and performance degradation of piezo-based active systems, as well as new concepts of structural health monitoring. Selected applications will be explained and discussed in detail elucidating the multiple possibilities of these materials especially in transportation industries.
