Abstract

Road vehicle suspension member for converting vibrations and/or mechanical stresses into electricity and a method for producing such a suspension member, the suspension member comprising at least one suspension element or at least one interface element, configured to participate in the fixing of at least one suspension element of the vehicle, and at least one continuous two-dimensional sheet, incorporated in or covering a surface of the suspension element or of the interface element, wherein the at least one two-dimensional sheet comprises at least one piezoelectric layer, comprising piezoelectric fibres collectively orientated in a common direction in such a way as to convert at least some of the vibrations and/or mechanical stresses undergone by the suspension element during operation of the vehicle into electricity, and an electrically conductive collector layer, covering the piezoelectric layer in such a way as to collect the electricity produced by the piezoelectric fibres.
