OBJECTIVE: Develop a low cost and high yield manufacturing method to fabricate textured piezo-ceramics for low frequency and high power underwater projector applications.
DESCRIPTION: Recent development of lead based piezoelectric textured ceramics, which have electromechanical properties between those of conventional PZT and relaxor crystals, has shown promise of improving acoustic transducer performance, relative to Navy Type III PZT. These materials have a high texture fraction (> 98%), a high d33 (> 600), and a loss factor of less than 10-2. The unique properties of textured ceramics have made it a material candidate for several Navy compact sonar systems, such as A-size sonobuoys. Given that sonobuoys are expendable sensors that require low per unit cost and high rates of production, it is in the Navy’s best interest that the cost of manufacturing textured ceramics is comparable (< 2X) to that of traditional PZT. This SBIR topic aims to support the emerging innovations in ceramics manufacturing with the potential to result in a high rate and high yield textured piezoelectric ceramics production line with a per unit cost comparable to traditional ceramics manufacturing.
PHASE I: Demonstrate with models, simulations, analyses or laboratory test results the viability of developing, through innovations in manufacturing processes, a 2X improvement in expected material yield for PZT ceramic material. The selected materials must be suitable for use in systems that use Navy Type III lead zirconate titanate. The improvement in expected yield should be measured relative to the vendor's current expected yields in production quantities. Develop a Phase II plan for implementing and demonstrating the proposed innovations into a prototype production system.
PHASE II: Develop the proposed prototype and demonstrate its viability for laboratory scale small batch production. Develop a plan for implementing the method at pilot scale production and demonstrating scalability from laboratory/benchtop results.
PHASE III DUAL USE APPLICATIONS: Successful development of this innovation is expected to increase incorporation of textured ceramic materials into Navy and commercial applications, such as sonar systems and medical devices, requiring high output or broadband piezoelectric devices.

The Navy Topic above is an "unofficial" copy from the overall DoD 22.2 SBIR BAA. Please see the official DoD Topic website at rt.cto.mil/rtl-small-business-resources/sbir-sttr/ for any updates.
The DoD issued its 22.2 SBIR BAA pre-release on April 20, 2022, which opens to receive proposals on May 18, 2022, and closes June 15, 2022 (12:00pm est).
Direct Contact with Topic Authors: During the pre-release period (April 20, 2022 thru May 17, 2022) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic. Once DoD begins accepting proposals on May 18, 2022 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period.
SITIS Q&A System: After the pre-release period, proposers may submit written questions through SITIS (SBIR/STTR Interactive Topic Information System) at www.dodsbirsttr.mil/topics-app/, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.
