介绍了一种宽带电磁振动转电微功率发生器。微型发电机能够在预定频率范围内产生稳定的功率。功率是通过电磁感应在谐振杠杆上制造的磁体和线圈之间的相对运动产生的。所报道的发生器通过实施多个不同长度的串联连接的悬臂梁来覆盖宽频带的外部振动频率，从而产生具有不同自然频率的悬臂梁阵列。该器件在4.2-5 kHz的外部振动频率范围内产生0.4 μ W的连续功率，电压为10 mV，覆盖800 Hz的频带。(c)2007 Elsevier B. V.保留所有权利。
This paper presents a wideband electromagnetic vibration-to-electrical micro power generator. The micro generator is capable of generating steady power over a predetermined frequency range. Power is generated by means of the relative motion between a magnet and coils fabricated over resonating cantilevers through electromagnetic induction. The reported generator covers a wide band of external vibration frequency by implementing a number of serially connected cantilevers in different lengths resulting in an array of cantilevers with varying natural frequencies. The device generates 0.4 mu W of continuous power with 10 mV voltage in an external vibration frequency range of 4.2-5 kHz, covering a band of 800 Hz. (c) 2007 Elsevier B.V. All rights reserved.
