In fact, the conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes, toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this purpose. In order to improve the performances of the converter, the polarization was specially studied with FEM simulations. A parametrized model was created. The electrical energy generated by the converter under an applied force was computed. The experimental results were shown for ceramic PZT. %G English %2 https://insu.hal.science/insu-01344710/document %2 https://insu.hal.science/insu-01344710/file/8_IREM2490b69e49e-dd37-40ab-b5f7-830dab82cc92.pdf %L insu-01344710 %U https://insu.hal.science/insu-01344710 %~ OBSPM %~ INSU %~ CNRS %~ UNIV-ORLEANS %~ CNES %~ OSUC %~ LPC2E %~ PSL %~ OBSPM-PSL
