abstract = "Currently, the shift of the resonant frequency of a PZT (Lead zirconate titanate) ceramic is required for pressure measurement. In order to measure the resonant frequency in each load, however, both a frequency generator and an impedance analyzer must be applied. The primary objective of this study is to develop a new methodology which is costeffective and simple, as compared to the currently-used method for pressure measurement, using a PZT ceramic. In the methodology developed herein, we have measured the change in the impedance of each load when a fixed frequency, the anti-resonance frequency, was applied to the PZT ceramic. Impedance changes can be measured according to changes of current via Ohm{\textquoteright}s law, and thus pressure was measured by voltage in the PZT ceramic. The load was increased from 0 kg to 3 kg, and the result, measured in voltage, and the experimental results yielded a regression equation of y=1.2069x+0.3706 and an r-square value of 0.9765.",
