Abstract:
1. A tyre provided with a device for detecting at least one functional parameter in the tyre, comprising: a substantially toroidal carcass structure defining a radially internal surface of the tyre; an anchoring body secured to the radially internal surface of the tyre; and a detecting unit comprising an antenna, a sensor unit operatively connected to said antenna, and a power supplier unit comprising a housing and a piezoelectric element, said power supplier unit being electrically connected with said sensor unit, wherein: the detecting unit and the anchoring body fit together by at least a rim portion engaging in a respective locking slot; said piezoelectric element is disposed within said housing so as to have a first end substantially fixed to said housing and a second end associated with a loading mass, a gap being formed between at least one inner wall of said housing and an outer surface of said loading mass; and said piezoelectric element is positioned substantially along a plane orthogonal to a radial direction of said tyre.
