Tire containing at least part of an electrical current generator intended for the supply of sensors and/or other electrical devices present within the tire, and method for manufacture the said tire

A tire for a vehicle wheel, comprising:

• a toroidal carcass;
• a tread band;
• and
• a first inductive element of an electrical generator;
• wherein the toroidal carcass comprises a pair of axially-opposing sidewalls terminating in beads allowing mounting of the tire on a corresponding rim,
• wherein the tread band is disposed on a crown of the toroidal carcass and axially extends continuously between the sidewalls,
• wherein at least one of the beads comprises an annular core comprising a matrix based on an elastomeric material or a plastomeric material,
• wherein the matrix incorporates fibers, yarn, or cords, and contains ferromagnetic material in at least one of a powder form or a fibril form, and
• wherein the first inductive element comprises at least one turn of conducting wire wound around a transverse profile of the annular core.
