Abstract: The invention relates to a system that generates energy from piezoelectric materials, applied mainly to supplying energy in traffic systems. The invention reduces the costs associated with the implementation of the piezoelectric systems on roads or vehicle and pedestrian transit systems, since in some cases they are manufactured in modules. It is characterized in that it is a system that includes a piezoelectric material, which generates electrical energy, a transmission network for said generated energy and a device for rectifying electrical current for the regulation and subsequent transmission thereof.
