In this work, we describe improvements in the performance of fiber-bending pressure sensors by using depressed cladding erbium doped fiber (DC-EDF). In this study, we compare the accuracy of DC-EDF sensor with bending sensor using standard single-mode fiber. Furthermore, we present a new technique to use this sensor in such way their response to pressure variation is dependent only with the amplified spontaneous emission (ASE) peak wavelength in S-band. In other words, we demonstrate that they are insensitive to the signal and pumping power variations.
