| Summary: | 碩士 === 義守大學 === 電機工程學系 === 100 === Today, it is well known that the mechanical energy could be gotten easily everywhere. The piezoelectric energy harvesting device could be gotten electric energy with piezoelectric effect from piezoelectric materials. Moreover, it can be saved electric charge and reached high efficiency of environmental protection.
In this project, we based on the foundation of wireless tire pressures gauge, and adopted COMSOL Multiphysics software from the foundation of Finite Element Method to build numerical module. According the piezoelectric material’s properties, the cantilever beam can be designed and simulated.
Before design the module, we had to investigate and discuss the theory of piezoelectric and Euler-Bernoulli. Then we employ the equation and first module with various structures to investigate the properties of the piezoelectric cantilever beam.
