摘要：

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.
