%X A new approach for packed FBG(fiber Bragg grating) pressure sensor using chemical bonding technics between polymer and FBG was proposed and demonstrated. A kind of chemical bonding material was used to strengthen the bonding between fiber and polymer in order to improve the pressure response of FBG sensor. This technics resolved the problem of avulsion in high pressure due to the big difference elastic modulus between polymer and fiber. The experimental result indicated that,within 0.04 MPa～0.6 MPa,the pressure response sensitivity was －4.48 nm/MPa and the resolution pressure measurement was ±0.01 MPa,which is 1463 times higher than that of the bare FBG. . The linearity of the temperature response curves is 0.9978.Reflection spectrum showed a steady figure through repeated measurement.
