Novel Low-frequency, Low-power Sonar Transducer for Undersea Navigation Navy STTR FY2012.A Sol No.: Navy STTR FY2012.A Topic No.: N12A-T016 Topic Title: Novel Low-frequency, Low-power Sonar Transducer for Undersea Navigation Proposal No.: N12A-016-0304 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: This work proposes to address the capability gap for low frequency, low power transducers in a small form factor. We propose to use newly evaluated resonance modes of single crystal piezoelectrics that provide savings of over 75% in transducer volume. The program will evaluate the shear mode material and be used in comparison with modeling and a prototype device to show operation below 100 Hz. Benefits: The primary benefit of the program is to provide significant miniaturization to low frequency sonar projectors. This work is applicable to location tracking, extremely low frequency communications and bathymetry. Commercial potential includes oil exploration. Return
