Self-contained Thin Multilayer Setback Piezo Generators for Powering Smart Fuzes

The objective of this proposal is to develop an innovative thin-multilayer setback piezoelectric generator (TM-SPG) to provide inertial harvested power for spin stabilized small-and-medium-caliber fuzing. The novel device introduces the key benefit of the thin-multilayer piezoelectric technology to meet the current needs of fuze electronics (i.e. high capacitance, low output voltage and high energy density) while providing a robust package to eliminate handling effects and facilitate the integration with the fuze electronics. During Phase I we have assessed and demonstrated the feasibility and benefits of the novel SPG technology. Proof-of-concept models and experimental data have proven the feasibility of meeting the energy density goals of the program, i.e. 40mJ/cm3, using optimization of existing technologies and futuristic designs. Phase II objective is to deliver a robust, design optimized, TM-SPG to meet Armys smart fuzing requirements for 25mm to 40mm caliber ammunition. Safety will be demonstrated by testing the unit under the MIL-STD-331 requirements.
