Abstract

Prototypes of a PZT-based ultrasound needle-actuating device have shown the ability to reduce needle penetration force and enhance needle visibility during needle insertion for tissue biopsy and regional anaesthesia. Further demand for smaller devices and the need for high performance transducers has motivated the investigation of a different configuration of needle actuation transducer, utilizing the d₃₁-mode of piezoceramic and exploration of further improvement in its performance using relaxor-type piezocrystal. This paper outlines the development of the d₃₁-mode needle actuation transducer design from simulation to fabrication and demonstration. Full characterization was performed on transducers for performance comparison. It was observed that the proposed d₃₁-mode transducer design has performance competitive with previous d₃₃-mode transducers. Furthermore, the needle actuation device is much more efficient after replacing PZT4 ceramic with PMN-PT piezocrystal.
