Abstract:

This SBIR program will address the modelling, fabrication, and testing of single crystal composite transducers. Comprised of single crystal relaxor-PT piezoelectrics, both single element and array configurations will be investigated for high performance medical ultrasonic imaging transducers. In collaboration with TRS Ceramics, Inc., single crystal relaxor PT piezoelectrics will be integrated into the transducer, providing ultra high electromechanical coupling (up to 92%), broad bandwidth, high sensitivity, and decreased impulse response for improved axial resolution. Using a one dimensional model, bandwidths of up to 130% have been realized. A direct comparison between an optimally designed single crystal relaxor PT composite transducer and an optimally designed PZT composite transducer will be made to demonstrate this performance enhancement. This Phase I research will provide a basis for further transducer optimization and cost effective manufacturing of an optimally matched broadband array in Phase II. A Phase I option for modelling, construction, and testing of an array element will enhance the development of the Phase II proposal.
