Laminate Materials

Magnetoelectric(ME) effect in magnetoelectric laminate materials have potential application in many fields. In this paper, Fe78Si9B13 amorphous ribbons /PZT/amorphous ribbons sandwich structure laminate materials were fabricated. By theoretical analysis and experimental verification, we studied systemically on the characteristics of the magnetoelecric laminate materials, such as optimized bias magnetic field of the ME effect, ME voltage coefficient at low frequency and the resonant frequency of the magnetoelecric laminate element. ME effect can be used to develop new ac magnetic sensor and other devices.

AbstractThe article is devoted to researching the practical application of the magnetoelectric effect for the development of energy harvesting devices, in particular for the design of magnetoelectric synchronous generator. The energy harvesting devices are designed to provide by the energy of remote or nonvolatile electronic devices that don’t require the high power consumption. General dimensions of the generator were as follows: diameter of 12 cm, thickness of 2.4 cm. The model of generator comprising eight ME elements with dimensions of one element of 40×10×0.5 mm at the frequency of the alternating magnetic field of 38 Hz provides the output constant voltage of 1.12 V and current of 3.82 microamps. Variable voltage before the rectifier was of 1.7 V. Total generated power was of 4.28 µW. The studies of resonant and non-resonant mode of ME element were carried out. Resonance mode of ME element provides a much greater output power. Designed generator can be applied in the construction of wind power sets, hydrogenerators, turbogenerators and other power generation equipment.
