摘要：

An improved FBG-type sensor for simultaneous measurement of force (or displacement) and temperature based on the bilateral cantilever beam(BCB) is proposed and demonstrated. The two parts of the beam are subject to opposite forces (or displacements) leading to a red shift for the part of the FBG subject to stretch and to a blue shift for the other one. An FBG bonded to the surface of the middle of the BCB is experimentally demonstrated to have a force sensitivity of similar to1.046 nm/N, a sensitivity of the displacement-based strain of similar to0.317 nm/mm, and a temperature sensitivity of similar to0.190 nm/degreesC between 0 degreesC and 70 degreesC, respectively.
