| Outline of Final Research Achievements |
In this study, it is proposed to laminate a piezoelectric lead zirconate titanate (PZT) element in order to greatly improve power generation characteristics of the PZT element, and the power generation theory of the laminated PZT element is derived. Optimal layer number deduced from the theoretical formula is 11 layers. In order to clarify the power generation characteristics of the laminated PZT elements using 1, 3, 5, 7 and 11 layers PZT elements, vibration power generation experiments are conducted. The experimental results are in good agreement with the theoretical values and the validity of the theory to vibration force of the laminated PZT elements was confirmed. Furthermore, experiments to drive the acceleration sensor module and the electronic device combining the temperature sensor and the radio transmission module using the 11-layer PZT element as a power source are performed. As a result of these experiments, it is confirmed that these electronic devices are normally driven.
