Abstract

Flexible magnetoelectric (ME) laminate composites consist of polyvinylidene fluoride (PVDF) and nanocrystalline alloy (FeCuNbSiB) were prepared. The ME coupling properties under different bending angle (θ) at zero dc bias magnetic field (Hdc) were investigated. The experimental results demonstrate the optimum zero-biased resonant ME voltage coefficient (MEVC) of ME laminate composites can reach 17.65 V/(cm·Oe). This is mainly due to the large permeability and low saturation magnetostrictive coefficient of the nanocrystalline alloy. The induced zero-biased ME voltages of ME laminate composites show an excellent linear relationship to ac magnetic field at bending states over a wide range. This laminate composite shows promising applications for high-sensitivity and small-size wearable magnetic sensors without bias.
