Paper Abstract

A novel hydraulic pressure sensor based on fiber Bragg grating and elastic metal film is proposed in this paper. Pressure sensing experiments are conducted after the finite element analysis of the sensor probe's structure. The experiments demonstrate that this kind of pressure sensor possesses good linearity and repeatability in its large measurement range with the sensitivity about 23.8 pm/MPa.
