Patent ID: 8578767

Claim:
A tire module for installation on an inner side of a pneumatic tire for vehicles, comprising: a device for measuring and/or monitoring of the air pressure in the tire; a transmitter for transmitting radio signals containing information about the air pressure in the tire; a mechanical-electrical converter having a bendable piezoelectric element, for converting, into electrical energy, alternating deformations of the piezoelectric element caused by the rolling tire; and a storage device for the electric energy, said storage device being connected to the converter, the converter comprising a circular, disc-shaped, piezoelectric element (piezo disc) and an electrical voltage generated by the piezo effect is tapped at contact points, situated on opposite sides of the piezo disc, wherein the piezo disc is arranged between a metal disc on the first side and a flexible conductor path foil on the second side of the piezo disc and wherein the conductor path foil, covering the first side of the piezo disc, forms a circular area connected to a circuit carrier by a strip, said strip comprising the conductor path foil and beginning from a rim of the circular area.
