在这项工作中，我们报告的非谐振压电微能量采集器的基础上，由氮化铝制成的波纹膜。这些收割机被设计为在低重复率下有效地响应非周期性机械冲击。非谐振系统的压电发电效率进行了比较，传统的谐振设备，如拉伸应力膜和悬臂梁。特别注意的是系统的性能，允许在低频率的粘性介质中的高阻尼操作。经典的分析建模被用来描述波纹微系统，目的是计算可行的能量输出和优化机电耦合。
In this work we report on non-resonant piezoelectric micro-energy-harvesters based on corrugated membranes made from aluminium nitride. These harvesters were designed to respond efficiently to aperiodic mechanical impact at low repetition rates. The piezogeneration efficiency of non-resonant systems was compared to conventional resonant devices like tensile stressed membranes and cantilevers. Special attention was paid to system properties that allow an operation at low frequencies in viscous media with high damping. Classical analytical modelling was employed to describe the corrugated microsystems with the aim to calculate the feasible energy outcome and to optimise electro-mechanical coupling.
