+The Piezoelectric Effect is the remarkable ability of certain materials to generate an [electrical charge](/wiki/charge) when subjected to mechanical stress. Conversely, applying an [electric field](/wiki/electric_field) causes these materials to subtly change shape, a direct coupling between electrical and mechanical energy.
