1. A component with an integrated sensor device for an optical, multi-axial measurement of a force application on the component, the component comprising:
a cavity;
a first support element having one or more first optical elements and a second support element having one or more second optical elements, the first support element and the second support element being formed in the cavity and being partially inserted into the component; and
a transmission device, which is configured,
to be connected to a power source and
to transmit, when connected to the power source, at least two beams in independent directions, the beams passing through the cavity between the first optical elements and the second optical elements, respectively,
wherein the first optical elements and the second optical elements are adapted to generate information about a relative position change of the first support element with respect to the second support element based on the at least two beams,
wherein the second optical elements include a mirror arranged in a second beam of the at least two beams,
wherein the mirror deflects the second beam between a parallel part that extends parallel to a longitudinal axis of the component and an inclined part that is inclined relative to the longitudinal axis of the component, and
wherein the transmission device is adapted to provide the information for measuring the force application.
