“…Piezoelectric materials generate an electric charge when rapidly compressed by a mechanical force during vibration or motion, such as from machinery or an engine. The early piezoelectric devices were based on natural monocrystalline materials such as quartz or tourmaline and Rochelle salt; however, the effect was relatively small [ 1 ]. Nowadays, piezoelectrics are based mainly on polycrystalline ferroelectric ceramics such as barium titanate (BaTiO 3 ) [ 2 ] and lead zirconate-titanate (PZT) [ 3 , 4 ], which exhibit larger displacements or induce larger electric voltages.…”
