Two models for energy harvesting system imparting rotational energy to piezoelectric materials are presented in order to compare the effects of applying identical amounts of energy to a cantilever beam by strain-changing and shock application. For a piezoelectric system given a high impulse with low displacement, higher power outputs were generated at lower resistive loads. Conversely, for a system...
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...
