<p>The field of energy harvesting has grown rapidly, with the huge development in low-power devices and Internet Things (IoT). With intent electrical for self-powered devices, piezoelectric technology is considered. In this study, we proposed several mechanical improvements to enhance produced through piezoelectricity. To determine best configuration harvest energy, three electric circuits were tested using a material (PZT-5H) mounted directly on vibration exciter. The harvested by each circuit was determined at different excitation frequencies, from 20 50 Hz, an amplitude 2 mm. favorable approximately 35 μJ frequency Hz. This subsequently used remaining aspects work. obtained fixed-free metallic plate used. First, free tried, imposing displacement values end plate. consisted materials: copper, aluminum, steel. PZT-5H positions material, position, displacement. highest around 6 μJ. Second, forced 0.5 mm 10 fixed lengths. 540 Third, showed that it possible further increase tuning resonance then 1010 results allowed optimizing toward supplying applications.</p>
