ABSTRACT:
The present invention relates to a sensor for measuring actual loads acting upon a surface of a mechanical component, wherein as a sensor an amorphous hydrocarbon layer with piezoresistive properties is used, which is preferably doped with at least one metallic and/or non-metallic element and is connected by contacts to a measuring device; the present invention further relates to the use of carbon layers having piezoresistive properties and preferably doped with metallic and/or non-metallic elements as a sensor for load measurements, as well as to a method of measuring actual loads at stressed surfaces of mechanical components, wherein as a measuring sensor an amorphous carbon layer preferably doped with metallic and/or non-metallic elements is used.
