Piezoelectric Effect

The Piezoelectric effect (/piːˌeɪzoʊˈilɛktrɪk/; from the Greek πιέζειν piezein, which means to squeeze or press, and ἤλεκτρον ēlektron, which means amber, an ancient source of electric charge) is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and electron which means amber, an ancient source of electric charge.

History

The piezoelectric effect was discovered in 1880 by French physicists Jacques and Pierre Curie. The Curies, however, did not predict the converse piezoelectric effect. The converse effect was mathematically deduced from fundamental thermodynamic principles by Gabriel Lippmann in 1881.

Applications

The piezoelectric effect finds useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, to drive an ultrafine focusing mechanism, and ultrafine microscopy techniques.
