Description
Summary:The relationship between deformation degree and curvature to the output voltage of piezoelectric system was analyzed. The calculated data and experimental data were compared. The experiment was held by using tip mass of 10 g, 20 g, and 30 g for the various thickness of piezoelectric material as 0.15 mm and 0.2 mm for various type design of supplemental plate. As results, at the vibration acceleration of 4 m/s 2 , the lowest average Ix value was resulted the highest voltage of 26.12 V. However, when the vibration acceleration of 40 m/s2, the lowest standard deviation of curvature ratio, ρ, and resulted the highest voltage of 58.98 V. This study proves that the deformation degree and curvature ration can be controlled.
