A Graphical Database for Streamlined Single Crystal Transducer Design Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-063 Topic Title: A Graphical Database for Streamlined Single Crystal Transducer Design Proposal No.: N081-063-1375 Firm: TRS Ceramics, Inc. 2820 East College Avenue State College, Pennsylvania 16801 Contact: Kevin Snook Phone: (814) 238-7485 Web Site: www.trstechnologies.com Abstract: Single crystal piezoelectrics promise to revolutionize underwater acoustic and ultrasonic transducers with broader bandwidths, greater resolution, greater range, reduced transducer size and weight, and reduced power requirements. However, there are many differences between the properties of single crystal and ceramic piezoelectrics which make it difficult to simply replace ceramic with crystal in existing transducer designs. For this SBIR program TRS propose to develop a user friendly, graphical program that will serve as a toolkit for transducer designers, allowing them to quickly evaluate a range of design parameters that have already been verified by established transducer models using a consistent data set. By implementing a database and simple model approach based on empirical data, various transducer types and parameters can be tested with limited prior knowledge of single crystal properties. Through the graphical interface, the user will be able to choose performance characteristics and observe output data and drawings of calculated transducer components. The Phase I program will focus on tonpilz transducers for sonar. Benefits: Single crystals present significant advantages over piezoelectric ceramics in a wide range of Navy sonar applications, however, since the materials properties are distinct from the ceramics it has been difficult for users to translate properties with performance of the material. By developing a user toolkit that provides a basis for quick, basic performance calculations, users will more quickly be able to see the advantages of single crystals, increasing commercial potential for the material. With quick access to performance curves, Navy contractors will be able to reduce development time and implement single crystal technologies in more systems. Return
