Abstract

The invention relates to a strain-measuring structure, comprising a carrier, which is divided into regions along the predetermined breaking points only after being joined to the object to be measured. After the separation along the predetermined breaking points, the regions individually joined in the joining zones can be moved freely relative to one another in the event of strain of the object, without the strain-measuring structure applying significant forces to the object to be measured, which could distort the strain measurement. Measuring assemblies for measuring strain lie between the regions. Said measuring assemblies can be based on different principles, depending on the application. The invention further relates to a method for producing the strain-measuring structure, to a method for measuring the strain of objects, and to the use of the structure to measure strain. The invention further preferably relates to a system comprising the strain-measuring structure and a control device for reading out and preferably activating and joining the structure.
