摘要： 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.

摘要： Fastened to a tyre is a detecting device consisting of a detecting unit including a sensor associated with an annular antenna having an inner perimetral edge, and an anchoring body having a base portion with a fastening surface secured to the radially internal surface of the tyre. The detecting unit is removably brought into engagement with the anchoring body by insertion of the inner perimetral edge of the antenna into a perimetral groove formed between the base portion and a retaining portion. The anchoring body has an overall height of about 0.2 to about 1.5 times a maximum distance measure between two mutually spaced apart points along the inner perimetral edge.
