This thesis is part of the Lab-TMEMS project, a collaboration between the GREMAN laboratory and the VERMON Company. The goal of this project is to realize miniaturized piezoelectric devices harvesting energy from low frequency vibrations in order to supply devices used in biomedical applications, for example. Thus, the objective of this thesis is to propose a strategy for the design and optimization of such devices. In order to achieve this objective, we have developed an original approach of modeling by finite element method in three-dimensional space in order to model the whole structure of the harvester. After being validated experimentally, our design tool is used to optimize the piezoelectric harvester according to given specifications...
