The present paper focuses on the energy harvesting based piezoelectric material from curved plate (CP). Thus, a FEM Model of CP is equipped with piezoelectric patches act as harvesters and connected in parallel with load resistor. The harvester’s positions have been obtained using new technique based on modal analysis maximum voltage output. The idea is to distribute patches all over the plate and then performing modal analysis. The harvesters position are then chosen based on the maximum output voltage extracted from the results. This new approach not just save time by avoiding iterative optimizations but also helps to use the needed harvester according to the applied load and its frequency. The methodology are check in time and frequency domain.
