[摘要]：We introduce the tin-modified and niobium-modified lead zirconate titanate ferroelectric ceramics as a micropower supplying source for integrated circuit chip. The ferroelectric ceramic phase transition under transverse shock wave compression can release the depolarization energy to the external storage capacitor. The porous microstructure ferroelectric ceramic micropower-generator is capable of generating low output voltage pulses with amplitudes 50.3 V and with transferred energy 1.12 mJ, and supplying integrated circuit chip with micropower sources. Theoretical calculations are conducted based on circuit analysis law, principle of dynamic high pressure, and shock wave physics, and the calculated response matches well with experimental data.
