AIP Conference Proceedings
Preserved Fulltext
This paper describes a wireless demonstrator system designed for generation and detection of fundamental symmetrical Lamb waves (S 0 ) characterized by high velocity and low attenuation. The demonstrator comprises two piezoceramic transducers embedded within an epoxy plate, drive and preamplification electronics, a microcontroller and a communications interface. This arrangement can be configured to operate in an active pitch-catch or pulse-echo interrogation mode or as a passive acoustic
