Ultrasound(US) is a longitudinal mechanical wave characterized by a frequency higher than 20,000 Hz. US generation is possible because of the discovery of the piezoelectric effect by the Curie brothers in 1880 and the inverse effect by Gabriel Lippmann one year later. The first concrete application for piezoelectric technology was during World War I, when, in 1917, Paul Langevin developed an ultrasonic submarine detector. Progress has led to the introduction of piezoelectric technology in all sectors. Concerning medical applications, the most significant is represented by US-based imaging and treatment.
