摘要

A novel class of piezoelectric-based event sensing and energy-harvesting power sources is presented for gun-fired munitions. The power sources are designed to harvest energy from firing acceleration and vibratory motions during the flight. The piezoelectric element may be used to measure setback acceleration level, indicate the barrel exit time and impact time and force levels for fuzing purposes. The developed power sources have the added advantage of providing safety, since the fuzing electronics are powered only after the munitions have exited the barrel. 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 120,000 G. In certain applications such as fuzing, the developed power sources have the potential of completely eliminating the need for chemical batteries. The design of a number of prototypes, including their packaging for high G hardening, and the results of laboratory, air-gun and firing tests are presented.
