(PZT-5) with middle bonding are investigated. With the configuration of middle bonding, the influence of interfacial epoxy layer decreases and the winglike ME structure demonstrates a ~2× higher ME voltage coefficient by a mechanical magnetic force coupled mode instead of shear force mode in the traditional layered composite. Moreover, the propose structure is easier to manufacture and has more stability with less epoxy adhesive. The winglike ME composite of FeCuNbSiB and PZT-5 achieves an ME voltage coefficient of 31.1 V/cm Oe when the length and thickness of FeCuNbSiB layer are 30 mm and 90 μm, respectively. These results provide the possibility of winglike ME composite for highly sensitive magnetic field sensing.
