Abstract :
A novel pressure sensor structure comprising a carbon fiber ribbon-wound composite cylindrical shell is presented in this paper. Based on this mechanical structure combined with a Fiber Bragg Grating (FBG), an accurate low-pressure sensor is developed. Theoretical analysis and first-principle investigations are conducted. Further, experimental results indicate that the pressure sensitivity and measurement range can reach 0.452 nm/MPa and 8 MPa, respectively.
