This application is a continuation of copending International Application No. PCT/DE01/01965, filed May 21, 2001, which designated the United States and was not published in English. BACKGROUND OF THE INVENTION Field of the InventionThe invention relates to an energy self-sufficient radiofrequency transmitter, the use thereof, and also to a method for the energy self-sufficient transmission of a radiofrequency signal. Energy self-sufficient systems in which mechanical energy is converted into electrical energy using a piezoelectric transducer and then rectified are known in the prior art. The electrical energy is used to drive simple resonant circuits. SUMMARY OF THE INVENTIONIt is accordingly an object of the invention to provide an energy self-sufficient radiofrequency transmitter and a method for the energy self-sufficient transmission of a radiofrequency signal that enable the communication of information to be improved. With the foregoing and other objects in view there is provided, in accordance with the invention, an energy self-sufficient radiofrequency transmitter, including: at least one electromechanical transducer; a rectifier circuit connected downstream from the transducer; a voltage converter circuit; a logic circuit configuration connected to the voltage converter circuit; a radiofrequency transmission stage connected to the logic circuit configuration; and at least one transmission antenna. The logic circuit configuration includes a sequence controller and a memory for storing an identification code. In accordance with an added feature of the invention, the electromechanical transducer includes at least one piezoelectric element. In accordance with an additional feature of the invention, the piezoelectric element is a bending transducer. In accordance with another feature of the invention, the electromechanical transducer includes at least one induction coil. In accordance with a further feature of the invention, the voltage converter circuit includes an energy storage element. In accordance with another added feature of the invention, the voltage converter circuit can be operated in a clocked manner. In accordance with another additional feature of the invention, there is provided, at least one capacitor for storing energy. The capacitor is connected between the rectifier circuit and the voltage regulating circuit. In accordance with a further added feature of the invention, the logic circuit configuration includes at least one component selected from a group consisting of at least one microprocessor and an ASIC. In accordance with a further additional feature of the invention, there is provided, at least one sensor connected to the logic circuit configuration. In accordance with yet an added feature of the invention, the logic circuit configuration is embodied using ULP technology. In accordance with yet an additional feature of the invention, the logic circuit configuration has clock generator including an LC resonant circuit or an RC resonant circuit. In accordance with yet another feature of the invention, the radiofrequency transmission stage is constructed for transmitting a radiofrequency signal having a frequency of greater than 1 MHz. In accordance with yet a further feature of the invention, the radiofrequency transmission stage is constructed for transmitting a radiofrequency signal having a frequency between 100 MHz and 30 GHz.
