提出了一种基于振动的具有软孔间隔环的驻极体能量采集器。这些收割机与最近引进的驻极体加速度计密切相关；然而，它们的开发目标部分不同。建立了地震质量为8~23g，表面电位为500V的各种收割机，并对其进行了特性测试，在约2 kHz的频率下测得功率高达8微瓦，加速度为1g。提出了一个分析模型，例如，它允许计算功率输出在给定负载电阻下的频率响应。最后，将实验结果与计算结果进行了比较。(C)2015 AIP出版有限责任公司。
Vibration-based electret energy harvesters with soft cellular spacer rings are presented. These harvesters are closely related to recently introduced electret accelerometers; however, their development targets are partially differing. Various harvesters with seismic masses from 8 to 23 g and surface potentials in the 500 V regime were built and characterized and powers of up to 8 mu W at about 2 kHz and an acceleration of 1 g were measured. An analytical model is presented which, for instance, allows the calculation of the frequency response of the power output into a given load resistance. Finally, experimental and calculated results are compared. (c) 2015 AIP Publishing LLC.
