La présente invention concerne un dispositif piézo-électromécanique pour récupérer l'énergie du transit de véhicules destiné à être positionné sur une surface routière. Le dispositif comprend : un élément magnétique (16) générant un champ magnétique, une bobine (17) comprenant des spires métalliques définissant un creux configurée pour recevoir l'élément magnétique (16), des moyens piézoélectriques (14) et des moyens mécaniques configurés de sorte que lorsqu'un véhicule transite sur le dispositif, il insère l'élément magnétique (16) dans le creux de la bobine (17) de manière à produire une première variation d'un flux magnétique lié aux spires de la bobine (17), afin d'induire une première tension électrique sur la bobine (17). Lesdits moyens mécaniques sont aussi configurés de sorte que lorsqu'un véhicule transite sur le dispositif, il transfère au moins partiellement une force du poids dudit véhicule sur les moyens piézoélectriques (14) de manière à les déformer. Lesdits moyens piézoélectriques (14) sont configurés pour générer au moins une deuxième tension électrique quand ils sont déformés.
The present invention concerns a device for recovering energy from vehicle transit destined to be positioned on a road surface. The device comprises: a magnetic element (16) generating a magnetic field, a coil (17) comprising metal windings defining a hollow configured to receive the magnetic element (16), piezoelectric means (14) and mechanical means configured such that when a vehicle transits on the device, they insert the magnetic element (16) into the hollow of the coil (17) so as to produce a first variation of a magnetic flux linked with the windings of the coil (17), such as to induce a first electric voltage on the coil (17). Said mechanical means are also configured such that when a vehicle transits on the device, they transfer at least partially a weight force of said vehicle onto the piezoelectric means (14) so as to deform them. Said piezoelectric means (14) are configured to generate at least a second electric voltage when they are deformed.
