- Abstract
- This study was conducted to analyze a relationship between deformation degree curvature and output voltage of piezoelectric system, as well as to interpret the calculated and experimented data. Basically, the experiment was conducted by using tip masses of 10, 20, and 30g to two different thicknesses of piezoelectric materials (0.15mm and 0.2mm). With this approach, the result showed that the lowest average I-x value had the highest voltage, 26.12 V m/s(2) when the vibration acceleration was 4m/s(2). On the other hand, the lowest standard deviation of curvature ratio, , had highest voltage, 58.98V when the vibration acceleration was of 40m/s(2). Overall, this study demonstrates that the deformation degree and curvature ratio are related and proves they can be controlled.
