摘要
In this research an energy harvester employing the magnetoelectric (ME) transducer to convert mechanical vibration energy into electrical energy is presented, and it is demonstrated that the use of a magnetically coupled cantilever beam can achieve to enhance the output performances of the harvester in terms of improving the electric output and tuning the resonant frequency efficiently. Under the acceleration of 0.2 g (with g = 9.8 ms(-2)), the resonant frequency is successfully tuned range from 16.1 to 27.9 Hz, and the output power is obviously improved from 42.3 to 151.4 mu W with the effect of magnetic coupling.
