Paper Abstract

This paper presents the first results on the use of the pre-stress to improve the performance of a magnetic field sensor based on a Terfenol-Fiber Bragg Grating integrated device. Indeed, since the pre-stress modifies the response of the magnetostrictive material, this should allow to fit the performances of the sensor to different operative conditions or to exploit also the stress as a control variable to optimize the design of the sensor.
