向与外界没有物理连接的远程微系统供电是困难的，使用电池并不总是合适的。本文提出的装置提供了一种解决方案，当嵌入振动介质中时，该装置从机械能发电。这个微型发电机的尺寸约为5x 5x 1 mm。分析预测，所产生的功率与振动频率的立方成比例，并且为了使发电量最大化，质量偏转应该尽可能大。假设偏转为50/spl mu/m，预测典型器件在70 Hz时的功率产生为1/spl mu/W，在330 Hz时为0.1mW。
Supplying power to remote microsystems that have no physical connection to the outside world is difficult, and using batteries is not always appropriate. A solution is offered by the device proposed in this paper, which generates electricity from mechanical energy when embedded in a vibrating medium. This micro-generator has dimensions of around 5x5x1mm. Analysis predicts that the power produced is proportional to the cube of the frequency of vibration, and that to maximise power generation the mass deflection should be as large as possible. Power generation of 1/spl mu/W at 70Hz and 0.1mW at 330Hz are predicted for a typical device, assuming a deflection of 50/spl mu/m.
