The Piezoelectric Effect History

The Piezoelectric History The direct piezoelectric effect, the production of electricity by the application of pressure, was discovered by brothers J. and P. Curie in 1880. The converse effect was predicted by Lippmann in 1881 and confirmed by the Curies in the same year. The major application of piezoelectricity was in Langevin’s work on submarine detection using quartz transducers to generate and detect underwater acoustic waves, started in 1917. Nicolson in 1919 described several devices, such as loudspeakers, microphones, and sound pick-ups based on the piezoelectric properties of Rochelle salt, and this was followed by Cady’s publication in 1921…
