Abstract

Air-coupled ultrasonic testing is required for inspection of materials where liquid acoustic coupling media cannot be applied, but transmission efficiency is a problem. Our group prototyped an ultrasonic probe fabricated using an array of piezoelectric ceramics rods by dicing a thickness-mode vibrator and the usefulness was found. However, a dicing method without rod broken was not established and unexpected frequency decrease of generated ultrasound was observed. In this study, we aim to improve the dicing method and reveal frequency-design guideline.
