| Résumé | Flexible ultrasonic transducers (FUTs) consisting of a 75 μm thick metal membrane, a piezoelectric composite with a thickness larger than 85 μm and a top electrode were developed for structural health monitoring (SHM) and non-destructive testing (NDT) applications. The piezoelectric films were made by a sol-gel spray technique. Its ultrasonic performance in terms of signal strength is at least as good as commercially available broadband ultrasonic transducers at room temperature. Onsite gluing and brazing installation techniques which bond the FUTs onto steel pipes for SHM and NDT purposes up to 100°C and 150°C are developed, respectively. The best thickness measurement accuracy of FUT at 150°C was estimated to be 26 μm. |
