Abstract: A tyre includes a flexible piezoelectric element associated with an energy storage device (e.g. a capacitor). The flexible piezoelectric element is mounted in cantilever-beam fashion within a housing so that a first end thereof is fixed to the housing. A loading mass is associated with the second end of the flexible piezoelectric element. A small gap is formed between the inner walls of the housing and the outer surface of the loading mass in order to allow limited flexure of the piezoelectric element. The housing, including the piezoelectric element, is mounted in a crown portion of the tyre, preferably on the inner surface of the tyre. The piezoelectric element flexes under the action of the longitudinal acceleration when the tyre rotates. Sufficient electrical power for powering an electronic device included within the tyre is obtained, together with a long durability of the piezoelectric element.

Abstract: A device for molding and vulcanizing a tire includes an outer shell, collapsible inner support, and movable crown. The movable crown is interposed between the outer shell and inner support. The movable crown and outer shell form a cavity of controlled volume for moulding and vulcanizing, wherein the controlled volume of the cavity fits a defined volume of the tire so that the moulding pressure is maintained within a predetermined range of values. A method of moulding and vulcanizing a tire includes preparing a tire on an inner toroidal support, disposing the tire and the toroidal support in an outer shell, and molding and vulcanizing the tire. Molding and vulcanizing are carried out in a controlled-volume cavity, wherein a volume of the controlled-volume cavity increases or decreases to adapt to a volume of the tire so that the volume of the controlled-volume cavity equals the defined volume of the tire.
