Abstract: The use of photonic sensors is gaining a large acceptance as an alternative to traditional electrical and mechanical sensors for monitoring of mechanical parameters. The potential impact of these sensors is related to their good metrological properties, small size and flexibility as well as the immunity from the electromagnetic field. This FBG might be implemented as a sensor to monitor the pressure produced by strain in any real medical application such as heart rate, ECG and respiratory status. In this study, we present an implementation of the FBGs sensor in a pressure waveform observer based on the strain phenomenon. The lab experimental results for FBG sensor demonstrate high sensitivity, very little error rate and an excellent linear relationship between the pressure corresponding to Bragg wavelength/shift. The obtained results having a Mean Absolute Percentage Error (MAPE) 0.00126%, sensitivity 0.1 Pm/μstrain and linearity factor 98.43%.
