The invention relates to a piezoelectric energy harvesting system (10) configured to be installed on a vehicle (1), characterized in that the system (10) comprises: —an inner panel (12); —an outer panel (14) slidably movable relative to the inner panel (12); —at least one deformable piezoelectric element (16) disposed between the inner panel (12) and the outer panel (14), said piezoelectric element (16) being capable of producing electrical power when it is deformed; —a plurality of impact elements (18) fixedly connected to the outer panel (14) and adapted to apply a compression force on the at least one piezoelectric element (16) when the outer panel (14) and the inner panel (12) are close enough to each other, said compression force causing a mechanical deformation of the at least one piezoelectric element (16); —repulsion means (22) adapted to move the outer panel (14) away from the inner panel (12); —an electrical power storage unit (24); —a one-way electrical circuit (26) connecting the at least one piezoelectric element (16) to the electrical power storage unit (24), said one-way electrical circuit (26) being adapted to charge the electrical power storage unit (24) with the electrical power produced by the at least one piezoelectric element (16) while preventing the application of an electrical charge to the at least one piezoelectric element (16) from the electrical power storage unit (24).
