Notes:
The electromechanical properties of a newly proposed 3-dimensional piezoelectrictransformer have been investigated. Especially, the effects of 3-dimensional geometry on themaximum tip displacement were carefully investigated. As a result, it was found that the maximumstrain of the 3-dimensional piezoelectric device was significantly enhanced up to 4.5 times higherthan that of a disk shape device. This data were in good agreement with the finite element modelanalysis of strains and vibration modes. Moreover, a very high voltage step-up ratio of 290 (10times higher than the Rosen type), sustaining efficiency more than 96%, were achieved
