Finite element analysis and experiments on Rainbow shape piezoelectric energy transferring elements
A designing structure which can harvest multi-direction vibration energies was proposed by using the new Rainbow shape piezoelectric energy transferring elements.In order to analysis and test the electricity generation of the piezoelectric energy transferring elements
the finite element analysis and practical tests were performed.The simulation results indicate that the open circuit voltage of Rainbow shape piezoelectric energy transferring elements will be reduced with the increases of the width and thickness of a metal substrate
the width and length of a piezoelectric film and the initial curvature radii of energy transferring elements; and it will be increased with the increase of the length of the metal substrate and shows a maximum with the increase of the thickness of piezoelectric film.The experimental result demonstrates the validity of finite element analysis and emphasizes that the open circuit voltage of energy transferring elements will have a maximum when the thickness of piezoelectric film is 0.25 mm.Furthermore
in the output power tests
the maximal output power of Rainbow shape piezoelectric energy transferring elements is about 7.75 W. The results of simulation and experiment provide helps for designing
manufacturing and realizing the Rainbow shape piezoelectric energy transferring elements.
