Piezoelectric effect

Piezoelectric effect refers to the application of an electric field to a crystal, which causes realignment of the internal dipole structure. This realignment results in crystal lengthening or contraction, converting electrical energy into kinetic or mechanical energy. This is how ultrasound transducers produce sound waves.

The reverse of the piezoelectric effect converts kinetic or mechanical energy, due to crystal deformation, into electrical energy. This is how ultrasound transducers receive the sound waves.
