Abstract
On décrit un appareil actionneur piézoélectrique et des méthodes qui procurent une rétroaction tactile. Un exemple dun ensemble actionneur piézoélectrique comprend une plaque de support avec une cavité évidée et un contact conducteur placé à lintérieur de la cavité évidée de la plaque de support. Un élément piézoélectrique possède une première couche composée dun matériau conducteur électrique et une seconde couche adjacente à la première couche constituée dun matériau piézoélectrique. Lélément piézoélectrique est placé dans la cavité évidée de sorte que la première couche met directement en prise le contact conducteur et la seconde couche doit être électriquement couplée à une mise à la terre à laide dun fil conducteur souple.
