摘要

压电材料在MEMS能量采集器中的应用不断增加，直接导致了对改进计算工具的基本需求，以便在设计层面优化性能。本文提出了一种精细而简单的模型，旨在为压电能量收集的多物理场问题提供快速而深刻的解决方案。主要目标是保留一个简单的结构模型(欧拉-伯努利梁)，并包含与设备实际三维形状相关的影响。全面介绍了分析模型，并与全三维计算结果进行了比较验证。

Numerical simulations of piezoelectric MEMS energy harvesters

The application of piezoelectric materials in MEMS energy harvesters is continuously increasing, with the immediate corollary of a fundamental need for improved computational tools in order to optimize the performances at the design level. In this paper, a refined, yet simple model is proposed with the aim of providing fast and insightful solutions to the multi-physics problem of piezoelectric energy harvesting. The main objective is to retain a simple structural model (Euler-Bernoulli beam), with the inclusion of effects connected to the actual three-dimensional shape of the device. A thorough presentation of the analytical model is presented, along with its validation by comparison with the results of full 3D computations.
