Abstract
The present invention relates to a rock bolt (100) having state monitoring for determining tensions or deformations in the form of a conductor track (104) attached to the bolt body (102), the electrical resistance of which conductor track changes proportionately to the tension/deformation. The conductor track can consist of electrically conductive inks which are applied directly to the bolt body by means of a printing process.
