  • Piezoelectric Ceramics - an overview | ScienceDirect Topics

    Ultra-sound imaging. Echography, endoscopy and intravascular investigations rely on piezoelectric ceramics (mostly PZT). The latter generates an acoustic wave into bodies in the 1–40 MHz range. Any interface in the wave trajectory infers that an acoustic signal is bounced back towards the probe, which can be tracked by the piezoelectric material used in this probe.
