Background:

• Autonomous ferroelectric generators (FEGs) utilize explosive-shock-wave depolarization.
• Previous FEGs used Pb(Zr(0.52)Ti(0.48))O(3) (PZT 52/48) ceramics.
• Further miniaturization of FEGs is a key research objective.

Purpose of the Study:

• To achieve further miniaturization of autonomous ferroelectric generators (FEGs).
• To investigate the use of high-energy density Pb(Zr(0.95)Ti(0.05))O(3) (PZT 95/5) ceramics in FEGs.
• To compare the performance of FEGs using PZT 95/5 versus PZT 52/48.

Main Methods:

• Utilized Pb(Zr(0.95)Ti(0.05))O(3) (PZT 95/5) ferroelectric ceramics as energy-carrying elements.
• Conducted a series of experiments comparing FEGs with PZT 95/5 and PZT 52/48 elements.
• Measured and compared output voltages of FEGs with varying PZT element sizes.

Main Results:

• FEGs utilizing smaller PZT 95/5 elements produced the same output voltage as larger PZT 52/48 elements.
• The output voltage of FEGs was found to be directly proportional to the thickness of PZT 95/5 samples.
• Successful miniaturization of FEGs was achieved by employing PZT 95/5.

Conclusions:

• High-energy density PZT 95/5 ceramics enable significant FEG miniaturization.
• PZT 95/5 offers superior performance, allowing for smaller energy-carrying elements.
• FEG output voltage scales directly with PZT 95/5 sample thickness.
