What is the difference between magnetostrictive and piezoelectric transducers?
In magnetostrictive transducers electrical power is used to generate an electro-magnetic field which causes a magnetostrictive material to vibrate. In piezoelectric transducers, electrical power is directly converted into longitudinal vibrations. For this reason, piezoelectric transducers have a higher conversion efficiency. This in turn reduces the cooling requirements. Today, piezoelectric transducers are prevalent in the industry.
