Outline
The PZT 95/5 ferroelectric ceramics with niobium doped was assembled into the shock-activated energy transducer. Based on the explosive-to-electric energy transfer theory, the large pulse of electrical current output was investigated under the action of shock wave in “normal mode”, and the electrical response of LRC load was discussed, especially for the small resistance (R) and small inductance (L) load. Several shock wave tests were conducted, and the PZT 95/5 ceramic stacks in parallel were devised to generate large pulses of electrical current. The maximum output current reaches above 5 kA, and the rising rate of the initial current is to 10~20 GA/s. The experimental results accord very well with the calculations.
