1. A system for generating electrical energy in a tyre for a vehicle, comprising:

  • at least one elongate piezoelectric element that generates electrical energy when deformed;

    wherein the at least one piezoelectric element is associated with the tyre,wherein a length of the at least one piezoelectric element extends in a longitudinal direction along at least a portion of a circumference of the tyre,wherein the at least one piezoelectric element is electrically connected to an electrical circuit that comprises at least one sensor other than the at least one piezoelectric element,wherein the at least one piezoelectric element supplies the generated electrical energy to power the at least one sensor other than the at least one piezoelectric element or supplies the generated electrical energy to a device that stores electrical energy,wherein the electrical circuit is not in electrical communication with the vehicle, andwherein the tyre is mounted on a rim of the vehicle.
