摘　　要：压电陶瓷自问世以来以其经济实用、结构简单的优点,得到了广泛的应用,现如今,利用压电效应制作而成的传感器被应用于生活的各个场景之中,桥梁隧道中多采用压电元器件为传感器提供电源。通过对单晶压电悬臂梁结构中的各个因素进行控制变量的研究,分析了不同的结构设计对压电俘能器件的电压或者相位带来的效益,得出了频率和尺寸之间的联系,对于不同阶次下的模态进行了阐述,同时总结了在实际的应用中,结构设计方面应注意的问题。The piezoelectric chips have been widely used due to its advantage of economic benefit and simply structure since it has been explored.And now,the sensors which are made of piezoelectric effect have been put into use in every aspect of life.In order to monitor the healthy status,people use the piezoelectric element to power the sensors in the bridges and tunnels.This paper made searches on some variables related to the cantilever beam with single piezoelectric chip,analysed the gain at various conditions,and expounded the modal at different orders.Fur-thermore,the problems which need to be focused in the practical application weresummarized.
