Abstract

The paper proposes a novel magnetic field sensor where a technique for hysteresis compensation is employed. The sensor integrates a magnetostrictive material with a Fiber Bragg Grating (FBG) strain sensor. Because of hysteresis and non-linear phenomena taking place in such materials, the sensor's performances may be sensibly reduced. To this aim, magneto-elastic material is accurately modelled in order to compensate hysteresis. in particular, the proposed approach allows to embed the compensation algorithm in the developed device, yielding to a more linear response of the sensor and to a reliable reconstruction Of magnetic field. Results are shown and discussed. (C) 2008 Elsevier B.V. All rights reserved.
