Weight measurements in a laboratorial environment are often affected by external factors from different origins, such as mechanical, thermal or electromagnetic effects. In this paper an innovative solution of a laboratorial weight measuring system somewhat circumventing these limitations is developed recurring to optical fiber Bragg grating (FBG) sensors embedded in a silicone rubber tray. As a result of the coupling between the FBG sensors and the low stiffness host material, the wavelength shift of the FBG sensors increases when the rubber tray is subjected to a transversal load. This paper reports the results obtained during the development and calibration of a prototype system for technology proof-of-concept.
