The converse magnetoelectric effect of an asymmetric Piezo-fiber/Metglas bilayer laminate composite subjected to DC electric voltage and magnetic field biases is presented. The experimental results indicate that positive voltages applied to the Piezo-fiber layer produce large tensile strains in the Piezo-fiber layer with relatively small compressive strains in the Metglas layer. The influence of DC electric voltage bias on the converse magnetoelectric effect is studies and it is found that an optimal DC voltage bias exists to maximize the CME coefficient related to the “jumping” stress/strain in the Metglas. The optimum DC magnetic field bias is shift by applying DC voltage biases and the magnitude of converse magnetoelectric response can be electrically tuned.
