Research on the Progress of Interdigital Transducer (IDT) for Structural Damage Monitoring

In the application of Structural Health Monitoring (SHM) methods and related technologies, transducer used for electroacoustic conversion has gradually become a key component SHM systems because its unique function transmitting structural safety information. By comparing analyzing health large-scale structures, theories based on ultrasonic guided waves are studied. The technologies research status interdigital wave arrays which damage detection introduced. fields transducers summarized. technical scientific problems solved by IDT Damage presented. Finally, development technology this project summarised.
