摘要

数字间换能器(IDT)因其工作频率可设计、成本低、频带可调、损耗低等优点，已逐渐应用于SHM系统中。为了验证环形IDT的最优几何尺寸和电极排列，将对最优尺寸的环形IDT进行仿真处理。根据仿真结果，提出了用精密电场驱动射流沉积3D打印机制备介电弹性体数字间换能器(DE-IDT)的方法。为性能实验提供了依据。

Preparation and Performance Simulation of Circular Flexible Interdigital Transducer

Interdigital transducer (IDT) has been gradually applied to SHM systems due to its designable operating frequency, low cost, adjustable frequency band, and low loss. In order to verify the optimal geometric size and electrode arrangement of the annular IDT, the optimally sized annular IDT will be processed by simulation. The precision electric field driven jet deposition 3D printer was proposed to prepare the Dielectric elastomer interdigital transducer (DE-IDT) according to the simulation results. Which provide a basis for the performance experiments.
