附录AEnergy Conversion and Storage Characteristics Research on Piezoelectric GeneratorThrough to the cantilever beam piezoelectricity electric power facility energy conversion characteristic theoretical analysis, has obtained the piezoelectricity Liang output voltage and the electrical energy theoretical model, but this is merely considers piezoelectricity Liang own factor alone to the power rate the influence rule. But in practical application, what often considered are the piezoelectricity electric power facility output, and its values size and the load resistance concern. Therefore, these rules have conducted systems research after the piezoelectricity electric power facility external connection loads output, and uses the different resistance number the load resistance to carry on the experimental confirmation.May discover by the second chapter of theoretical analysis, although piezoelectricity Liang can produce the great voltage, but it each time distorts the electrical energy which outputs to be very limited, still could not meet the modern mostly electronic installations need. This chapter while carries on the theory and experimental study to the piezoelectricity electric power facilitys output, but also has conducted the memory characteristic research through each kind of storage medium to the piezoelectricity electric power facilitys power rate. May know by the second chapter of piezoelectric vibrators basic theory knowledge, piezoelectric ceramics’ electricity characteristic equivalent circuit may be represented as the electric charge equivalent circuit. And, piezoelectric ceramics’ dielectric resistance was opposite in the external load, the resistance number was big, might neglect. In the above two kind of situations theoretical calculation formula may see, in practical application, regardless of the piezoelectric vibrator uses what connection mode, can have a best load resistance, causes its output maximizing.At the same time, for the confirmation theoreti
