METHOD FOR GENERATING ELECTRIC ENERGY IN A TYRE

摘要

Method and system for generating electric energy in a tyre wherein: a device comprises a housing that extends according to a longitudinal axis X, at least one electrical winding, a magnet movable within the housing along said longitudinal axis X, and a force providing element positioned at at least one of two opposite ends of the housing, which is adapted to exert on the magnet a force along said longitudinal axis X; the device is fixed on a crown portion of the tyre; the tyre is rotated on a rolling surface so as to determine variations of forces that act on the device every time the device passes, due to the rolling of the tyre, at a footprint of the tyre; the force exerted by the force providing element and said variations of forces along said longitudinal axis X are exploited so as to cause variations of the magnet position with respect to the at least one electrical winding; and the electric energy generated across the at least one electrical winding as a consequence of said variations of the position of the magnet with respect to the electrical winding is collected.
