APPARATUS FOR AUTONOMOUS POWER SUPPLY OF POWER-USING DEVICES LOCATED IN THE PROXIMITY OF A ROAD, AND PROCESS THEREFOR

摘要

A device for autonomous power supply of power-using devices set in the proximity of a road, along which vehicles travel, includes one or more electric-current generator elements of a piezoelectric type. The device includes at least one structural element configured for being deformable in an elastic way in at least one direction in response to a perturbation of the environment adjacent to the path of a vehicle that is travelling. The at least one structural element includes at least one area of deformation. The electric-current generator element of a piezoelectric type is associated to the area of deformation.
