ABSTRACT:
A method of manufacturing state transducers for mechanical components intended to be subjected to wear, mechanical and/or thermal loads, especially state transducers for tools. The invention is characterized in that electric conductors and, where appropriate, electronic circuits (9) of microscale for measuring wear, mechanical and/or thermal loads are applied on the surface of the component (11), and a protective layer (10) is applied upon at least portions of said circuits (9) and conductors, where said conductors, circuits and said protective layer (10) are applied so as to constitute a unit atomic integrated with the mechanical component (11), which conductors and circuits are intended to be connected to a signal processing or corresponding equipment. The invention also comprises a mechanical component treated according to said method.
