  • Patent number: 8387452
    Abstract: A tire 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 tire, preferably on the inner surface of the tire. The piezoelectric element flexes under the action of the longitudinal acceleration when the tire rotates. Sufficient electrical power for powering an electronic device included within the tire is obtained, together with a long durability of the piezoelectric element.

  • Patent number: 8316700
    Abstract: An oscillating structure is coupled to a crown portion of a tire. The oscillating structure includes a housing and a piezoelectric element coupled to the housing. The piezoelectric element is able to oscillate in an oscillation direction, which could match either a longitudinal or a radial direction of the tire. An electrical signal generated by the piezoelectric element is processed so as to determine at least one operating parameter of the tire. The processing includes determining whether a rotation speed of the tire is greater than a threshold speed; and, in the negative, extracting information for determining the at least one operating parameter of the tire from a low-pass filtered signal. Such low-pass filtered signal is obtained by removing at least frequency components of the electrical signal having a frequency higher than or equal to a resonance peak frequency of the oscillating structure.
