Cost-Effective PiezoCrystal Transducer Assembly Technologies Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-092 Topic Title: Cost-Effective PiezoCrystal Transducer Assembly Technologies Proposal No.: N101-092-0639 Firm: Materials Systems Inc. 543 Great Road Littleton, Massachusetts 01460 Contact: Barry Doust Phone: (978) 486-0404 Web Site: www.matsysinc.com Abstract: The objective of this program is to devise and demonstrate innovative materials processing methods for the cost-effective fabrication of relaxor piezoelectric single crystals into complex sonar transducer assemblies. MSI has chosen to focus on fabrication issues in mid to high frequency transducers involving PiezoCrystal composite materials, using its established base of ceramic piezocomposite transducer assembly methods to leverage development of a line of broadly-applicable PiezoCrystal transducer assembly technologies. In Phase I, MSI will develop cost-effective techniques for producing robust PiezoCrystal composite. Highly conductive, mechanically and electrically robust electroding techniques will also be developed based on MSI''s established ceramic composite expertise. In Phase II, MSI will extend the Phase I processing techniques to include lamination of a variety of materials including polymers and metals so that a variety of Langevin style (thickness mode resonator) transducers can be produced. Benefits: Upon successful completion of Phase II, MSI will have adapted its established composite transducer manufacturing processes for fabricating PiezoCrystal composite transducers capable of meeting a wide range of Navy sonar requirements. The combination of these processes will allow MSI to cost-effectively fabricate and manufacture high performance transducers with increased output and bandwidth utilizing PiezoCrystal composite materials.
