摘要
The present invention relates to an energy harvesting magnetoelectric composite laminate for a power supply for driving electric power wire sensor which includes a piezoelectric single crystal layer; and a magnetostrictive layer formed on one surface or both surfaces of the piezoelectric single crystal layer of a magnetostrictive material. The energy harvesting magnetoelectric composite laminate for a power supply for driving electric power wire sensor according to the present invention supplies electric power to a sensor through energy harvesting which generate electric power based on a magnetic field parasitic at a circumference of a power line and/or mechanical vibration energy at the circumference of a power line, so that the power may be continuously and stably supplied to semi-permanently operate a sensor node without any complicate periodic exchange of a power source and in addition, the extension of a life cycle of a sensor node and the reliability of sensed data may be improved. Thus, the practice of a USN based system such as a power line remote monitoring system may be advanced.;COPYRIGHT KIPO 2016
