Abstract
An optical measuring element measures forces in at least one direction. The measuring element has a single-piece structure. There is an outside wall with notches introduced therein. Each notch defines parallel edges, and the notches define more or less elastically flexible zones in the structure and constitute the only connection between a first region and a second region of the structure. For optical distance measurements between the two regions of the structure, one or more optical fibers are each attached with one end thereof to a region of the structure such that reflective surfaces are located close to the ends. The reflective surfaces are firmly connected to another region. The optical fibers are disposed on the outside wall.
