A measuring system based on flexible silicone waveguides is presented in this work. A proof of principle of the bending-loss sensing unit was performed in a previous work [3]. The subject of this paper is to report different sensor designs, fabrication, as well as the linear response of the sensing unit in a predetermined force range. The linear behavior was achieved by a multimode waveguide design and the associated fabrication method for the waveguides of the sensor unit.
