Piezoelectric and magnetostrictive materials perform volume-invariant changes in their length byapplying an external control field. This behaviour can be implemented to realize solid-statetransducers. The maximum strain is in the range of 0.1 to 0.2%, the generated forces can result inthousands of ...
The ME effect can be enhanced by adopting the suitable magnetostrictive and piezoelectric materials. However, they are restricted by the individual properties of the materials. The most severe limitation results from the dependence of the piezomagnetic coefficientd33on dc bias field (Hdc). As this ...

Prior to FeNi coating, a 50 nm SiO2 film was deposited on the piezoelectric substrate to provide a well protection on interdigital transducers (IDTs) in procedure of FeNi coating. The FeNi film produces magnetostrictive strain stimulated by the electromagnetic field, where the thickness, density ...

There are three kinds of commonly used ultrasonic methods for guided wave generation; namely, piezoelectric, electromagnetic, and pulsed laser methods. 2.1. Piezoelectric Transducers Guided wave excitation by the piezoelectric method is very common in practical applications [48,49]. A piezoelectric ...
