Abstract :
Compared to conventional piezoelectric sensors, fiber Bragg grating (FBG) sensors have many advantages. This paper reviews the development of FBG pressure sensor. The features and application scopes of several types of pressure sensors are discussed. We designed a FBG pressure sensor based on a thin-walled cylinder. The relationship between the central wavelength of FBG and the pressure is derived. The experimental pressure sensitivity is 0.079nm/MPa, and the linearity of sensor is 0.999. Through the discussion of fiber properties, compression sensitizing techniques of FBG is proposed.
