Abstract

A novel class of piezoelectric-based energy-harvesting power sources is presented for gun-fired munitions and other similar applications that require very high G survivability. The power sources are designed to harvest energy from the firing acceleration as well as vibratory motion of munitions during the flight and convert it to electrical energy to power onboard electronics. The developed piezoelectric-based energy harvesting power sources produce enough electrical energy for applications such as fuzing. The power sources are designed to withstand firing accelerations in excess of 100,000 G. In certain applications such as fuzing, the developed power sources have the potential of completely eliminating the need for chemical batteries. In fuzing applications, the developed power sources have the added advantage of providing additional safety, since with such power sources the fuzing electronics are powered only after the munitions have exited the barrel and have traveled a safe distance from the weapon platform. The design of a number of prototypes, including their packaging for high G hardening, and the results of laboratory and air-gun testing are presented. Methods to increase the efficiency of such energy-harvesting power sources and minimize friction and damping losses are discussed.
