Abstract :
A magnetoelectric (ME) composite consisting of FeCuNbSiB foils, Terfenol-D plates, piezoelectric PZT plates, and an H-shaped elastic substrate has been developed. The H-shaped elastic substrate severs as the multipeak frequency determining element. Due to the coupling between the H-shaped elastic substrate beams, an enhancement in the multipeak ME effect can be obtained compared with the conventional composite using a rectangle elastic substrate. The ME coefficient of the composite with two PZT plates electrically connected in series reaches 58.2 V/cm·Oe, which is ~4 times higher than that of the ME composite with the rectangle structure. The multipeak ME effects, along with the giant ME coupling, can be used in multifunctional devices, such as broadband energy harvesters or magnetic field sensors.
