摘要：
The development of an optical fiber based pressure sensor, created using a Fiber Bragg Grating (FBG) and a glass fiber reinforced polymer membrane for use in aerodynamic applications, is reported. The FBG was co-bonded on the surface of the membrane to measure the strain induced by the deflection of the diaphragm with applied pressure. The sensor exhibited high sensitivities of 56.7 pm/kPa, with a minimum resolution of 21 Pa over a 0 to 35 kPa range. The outputs from a mathematical model, Finite Element analysis and the experimental results are compared and discussed.
