Piezoelectric effect

Piezoelectric effect refers to applying an electric field to a crystal, which causes realignment of the internal dipole structure resulting in the crystal to lengthen or contract. The process converts electrical energy into kinetic or mechanical energy.

The reverse of the piezoelectric effect converts kinetic or mechanical energy, due to crystal deformation, into electrical energy.
