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.
