Abstract

The fluctuating force from the dynamic system applied to the piezoelectric material gives electric energy as an output. In the present work, the effect of pressurizing the diaphragm type piezoelectric elements at the same time and at a different time (depicting the condition of in-phase and out-of-phase) has been studied. Furthermore, to combine the outputs, the use of series and parallel circuitry has been studied before the rectification (AC to DC) and after the rectification. The material of the piezoelectric used in the experiments was lead zirconate titanate (PZT). The maximum power output of 362.8 µW is obtained when the two piezoelectric elements were pressurized in-phase by a cyclic force of amplitude 400 mA and 17 Hz frequency, their signals rectified and then combined through the parallel circuit. The high power output is at the natural frequency of the mechanical system.

压电陶瓷在不同增压条件和电路下的性能研究

动力系统施加到压电材料上的波动力产生电能作为输出。本文研究了膜片式压电元件在同一时间和不同时间(描述同相和非同相情况)的加压效果。此外，为了组合输出，在整流之前(交流到直流)和整流之后，研究了串联和并联电路的使用。实验中使用的压电材料为锆钛酸铅(PZT)。在振幅为400 mA、频率为17 Hz的循环力作用下，对两个压电元件进行同相加压，并将其信号整流后通过并联电路组合，可获得362.8µW的最大功率输出。大功率输出处于机械系统的固有频率。

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
