| Abstract: | A fiber Bragg grating pressure sensor with high sensitivity used as the pressure underlay on thin-wall straincanister for oil down-hole is advanced. The experimental result shows that its pressuresensitivity is 1.23×10-4 MPa-1,several times higher than that of any other fiber Bragggrating sensors reported previously. |
