Bilayer PVDF/Metglas laminates with remarkably anisotropic ME coupling effect have been fabricated. By a careful evaluation of these anisotropic behaviors both experimentally and theoretically, we demonstrate that an ultra-sensitive detection of weak dc magnetic field and its spatial orientation is practically applicable using the bilayer PVDF/Metglas laminate. This magnetic field probe has quite high sensitivity. The reason for such a high magnitude and orientation-dependent magnetoelectric coupling is explained. (C) 2009 Elsevier B.V. All rights reserved.
