A device and a system for measuring forces

Optical transducers are provided according to the present invention for detecting forces such as, for example rotational and transversal forces acting on them, wherein, for the purpose of detecting said forces, optical signals (4a, 4b) are transmitted through an optical path defined by optical fibers (2a, 2b). Moreover, optical means (3) are provided, adapted to modify the transmission of the optical signals through the optical path, as a result of forces acting on them. The resulting optical signals exiting the transducer are then used for the purpose of detecting the forces acting on the transducer.
