Development of Magnetostrictive Energy Harvesting of Mechanical Vibration Energy Navy STTR FY2010.A Sol No.: Navy STTR FY2010.A Topic No.: N10A-T020 Topic Title: Development of Magnetostrictive Energy Harvesting of Mechanical Vibration Energy Proposal No.: N10A-020-0221 Firm: Applied Physical Sciences Corp. 475 Bridge Street Suite 100 Groton, Connecticut 06340 Contact: James McConnell Phone: (860) 448-3253 Web Site: www.aphysci.com Abstract: Applied Physical Sciences and the University of Maryland propose to develop a magnetostrictive transducer that harvests electrical energy from shipboard machinery while simultaneously suppressing vibration to improve the ship's stealth characteristics and thereby improving the performance of hull mounted sonar systems. Analysis performed during the Base Effort will provide an initial design specification for the transducer and associated energy harvesting circuit wherein the overall size, transduction mode, power level, and efficiency are specified in terms of the machine's fundamental forcing frequency, power rating, and weight. A proof-of-concept experiment performed during the Option is expected to provide initial validation of the overall concept and lay a foundation for further development and experimentation during Phase II. Benefits: Provide a local source of electrical power for condition based monitoring sensors and wireless telemetry networks aboard Navy vessels. Improve stealth characteristics and hull mounted sonar systems aboard Navy vessels. Return
