Abstract

A component has an integrated sensor device for an optical, multi-axis measurement of a force applied to the component. The component includes a cavity and 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 are formed in the cavity and partially inserted into the component. A transmission device generates at least two beams in independent directions when connected to a power source. The beams pass through the cavity between the first optical elements and the second optical elements. The first optical elements and the second optical elements are adapted to generate information about a relative positional change of the first support element with respect to the second support element based on the at least two beams. The transmission device provides the information for measuring the force application.
