1. Strain measurement device for electrically determining a strain of a basic body, said device comprising:
a carrier film which can be applied to the basic body,
an electric measuring loop printed onto the carrier film of conductive printing paste, which has a measuring element for generating an electrical signal based on the strain and which has four conducting tracks connected to the measuring element for four-wire sensing, each of the four conducting tracks having an electrical conductor connection, and
wherein the conducting tracks, the conductor connections and the measuring element are printed with the same printing paste.
