This research focuses on macrobendingbased fiber optic sensor technology for weight measurement. The sensor was constructed using fiber optic patch cable wrapped on a cylindrical rubber structure. This work analyzes the impact of the patch cable’s jacket application and the integration of a protective layer coated on the sensor. Moreover, the variations of deformer/impactor type, comprised double-flatshape (DFL), double-cylindrical protrusion-shape (DCP), double concave bowl-shaped (DCB), and a combination of a cylindrical-protrusion and a concave bowl-shape (CP-CB), were subsequently examined. The findings highlight the range of the optical loss that is attributed to weight measurement capacity. The investigation unveils the largest weight capacity demonstrated by the application of the DCB deformer type, i.e., reaching ~160.1 kg. The utilization of DCP, CP-CB, and DFL performed a weight capacity until ~41.3 kg, ~64.5 kg, and 121.2 kg, respectively. All deformer examination was employed on the sensor structure without the patchcable’s jacket and protective layer. The results can be used as a consideration in the construction of a macrobending-based fiber optic sensor for weight measurement, ensuring its adaptability and efficacy in real-world conditions.
