Özet

The design, fabrication and application of flextensional composite transducers are summarized in this study. The moonie and cymbal type flextensional transducer consist of a ceramic driving element sandwiched between two truncated conical metal or plastic endcaps. These transducers can be used as both sensors and actuators. Piezoelectric, electrostrictive and antiferroelectric-ferroelectric switching types of ceramic can be used as the driving element in either single layer or multilayer form. In the cymbal and moonie transducer designs, the flexibility and durability of metals and the driving power of the ceramic element are combined.
