MSI (Materials Systems Inc.) designs and manufactures custom sonar transducers and arrays for a wide range of applications, including harbor defense, side-scan, obstacle avoidance, sub-bottom profiling, swath bathymetry, mine hunting, swimmer detection, and acoustic communications. MSI’s piezocomposite technology offers extremely broad bandwidth, high receive sensitivity, high source levels, conformability for curved arrays, and reduced side lobes.

Our core strength lies in our ability to understand our customers’ sophisticated systems requirements and provide a complete solution that integrates engineering and innovative design with high or low volume manufacturing. Our staff is comprised of individuals with backgrounds ranging from mechanical, electrical and acoustical engineering to materials science and physics. This technical breadth enables us to provide a complete range of services to meet your requirements, including: * Custom product design * Engineering and measurement * Prototyping and development * Low or high volume manufacturing

MSI has become the recognized leader in providing high performance piezocomposite transducers for the US Navy and a variety of other defense and commercial applications. This is a mature technology that has been demonstrated on a wide range of applications. MSI is in full scale production on a variety of commercial and industrial customers. MSI is ISO 9001:2008 certified.


MSI’s piezocomposite arrays deliver broad bandwidth, enabling broad spectrum (chirp) and multi-frequency operating techniques which provide greater resolution. MSI’s piezocomposite arrays can also be curved and shaded to achieve a specific beampattern or to achieve a hydrodynamic profile when mounting the arrays to the curved hull of a vessel or AUV. Resonant transmit designs are in production at frequencies ranging 12 kHz to 1MHz. Receive arrays cover this same range and more, operating as low as 3 Hz in long-range surveillance arrays. MSI’s piezocomposite arrays have been shown to meet full explosive shock requirements for Navy operations in both the USA and UK, and can be configured for full ocean depth performance.

MSI also has ongoing R&D efforts to further develop sonar technology. Currently MSI has a number of R&D projects developing single crystal piezoceramic and piezocomposite technology for use in sonar transducers and arrays. Single crystal materials provide wider bandwidth and higher sensitivity than current piezoceramic and piezocomposite technologies.

MSI’s piezocomposite array technology is providing major performance and cost benefits to many of the latest commercial and defense imaging systems currently being deployed while our R&D efforts are setting the groundwork for tomorrow’s sonar systems.
