Abstract Translated from French L'invention a pour objet un dispositif de détection d'une pression. Le dispositif comprend un élément piézo-électrique 3 en PVF2 pourvu d'une électrode centrale 1 et d'une électrode extérieure cylindrique 2. L'ensemble est noyé dans un profilé souple 5 de sorte qu'une pression appliqué sur le profilé est transmise à l'élément 3. L'invention trouve une application dans la détection du passage de véhicules sur une route, par exemple pour commander les signaux réglant la circulation.
