The fuze of induction settable at muzzle demands its power supply can provide electric energy to fuze circuit normally. The multilayer piezoelectric power supply has the characteristics of resisting high over loading, instantaneous activation time and high output energy. The principle of multilayer piezoeletric power supply was studied, and the formulas of its output energy, voltage and energy diversion efficiency were deduced. The static tests and dynamic impulsion experiments indicate that its activation time is smaller than 200 μs, and its output energy achieves 31 mJ. The power supply can provide electric energy to fuze circuit for a few seconds.
