The concept of smart systems is based on intelligent materials, which are changing local mechanical properties on external stimulation. Due to the overall performance, piezo ceramics are considered as the most promising basis for active materials. The use of thin monolithic piezo ceramic wafers and fibers as actuating and sensing material has been discussed in many publications. Piezo ceramic fiber based composites have become available on industrial scale during the past years. Examples of piezo fiber composites devices are the AFC - actuators (Active Fiber Composites) and the MFC - actuators (Macro Fiber Composite) actuators and 1-3 type composite transducers. This has stimulated the development of new applications for piezo fiber composites recently. The present paper is giving an update on availability and developments of the MFC for smart systems. Beside the intended use of these devices as actuators, new design forms have been investigated in order to qualify piezo fiber composites for sensor applications, especially as strain gages and pressure sensors as well as for energy harvesting. This paper gives also an update of emerging applications for piezo fiber composites and new devices under development to accommodate these applications.
