In this work, the dependence of the magnetostrictive response on the prestress has been used to improve and fit the performance of Terfenol-D based fiber Bragg grating magnetic sensor. The possibility to tune sensitivity allows to work at different operative conditions and to develop advanced sensors with reconfigurable sensitivity. Performance improvements in terms of magnetic resolution up to 0.0116 A/m have been demonstrated.
