Paper Title:
Generating Characteristics of a Cantilever-Type Unimorph Piezoelectric Generator Depending on the Material and Mass
  Abstract

Structure of a cantilever-type unimorph piezoelectric generator was proposed and designed so as to allow the generator to resonate at frequencies lower than commercial frequencies. This generator is capable of generating amount of voltage its despite low frequency and simple fabrication that result from its simple structure. In this paper, the resonance characteristics of the generator depending on significant parameters were determined through a modal analysis and the influence of each parameter was analyzed to define each its level of sensitivity on the high output characteristics using ANSYS, a FEM program. The generators resonated at frequencies lower than 60 [Hz], as determined through the FEM results. The generating characteristics were then defined by implementing vibration experiment and comparing the results with those from the analysis. The resonance frequency and output power depending on changes in the mass and material were determined by the analysis.
