Experimental research on piezoelectric ceramics activating micro-sized thermochemical battery

To verify feasibility of piezoelectric ceramic activating micro-sized thermochemical batteries, it is very necessary to disclose shock pressure and electric output performances of piezoelectric ceramic. In order to simulate piezoelectric ceramic activating micro-sized thermochemical batteries in the bore, shock pressure, and electronic output testing systems for piezoelectric ceramic have been established. And the piezoelectric ceramics composite structural targets are impacted using one-stage light gas gun to load projectile, which is used to simulate the overload of the projectile with piezoelectric ceramics during projectile launching process, and combining with the experimental tests of a military 3# electric fuse head as a firing component in series. In experiments, the composite structural targets (front steel substrate-piezoelectric ceramic-rear steel substrate) are vertically impacted by the cylindrical 2A12 aluminum projectiles. The change rules of shock pressure, output voltage, and current peak values for piezoelectric ceramics are obtained at the different experimental parameters, and the firing conditions of piezoelectric ceramic igniting the military 3# electric fuse heads and ignition paper are presented.
