Development of Multilayer Parallel Connected Piezoelectric Ceramic Power Supply and Measuring Instrument for Electricity Generating Performance

摘要：

Study the principle of a new type of multilayer parallel connected piezoelectric power supply. The output electrical energy increases and the amplitude becomes maximum when piezoelectric ceramic stack occurs resonance,the formula of natural frequency is deduced through theory method. In order to measure and study the electricity generation performance of the piezoelectric ceramic power supply,develop a measurement instrument for the electricity generation capacity of the piezoelectric ceramic power supply. In the design of this measuring instrument,use a changing polar distance capacitance microdisplacement sensor to measure the vibration amplitude of piezoelectric ceramic stack use a charge amplifier to measure the generated quantity of electricity,and the real experimental results of measurement instrument are displayed. The measurement instrument is developed to analyze the influences of the size and structure parameters of the piezoelectric ceramic and the frequency and the amplitude of the external excitation on the electricity generation performance of piezoelectric ceramic power supply.
