| This study is aimed to analyze a piezoelectric energy harvesting system made of a smart lead zirconate material applied to the hybrid excitation in the form of mechanical vibrations and airflow. The system utilized a monolithic PZT plate composed of ceramic-based piezoelectric material, under its bending, the voltage is generated. In the experiment, a specialized measurement system based on Arduino and wind tunnel were used to conduct the tests on a bluff-body shape mounted on an elastic beam with a piezoelectric attached to a support with arms. The elastic beam and arms were linked with springs, that change the internal characteristic frequency of the energy harvester. The air-flow velocity and forced vibration frequencies were varied, and the output voltage signal and linear accelerations were recorded during the variable excitation. The effect study is the conclusion that the system’s highest voltage efficiency was achieved through a combination of mechanical vibrations and air flow. Additionally, the study generated the correlation between the RMS voltage as a function of the air-flow velocity for resonance excitation frequencies. In the study, the area where the system could generate the highest output voltage under given excitation conditions was investigated. The above-described comparative analysis is conducted for two research objects differing in their mass. The proposed energy harvesting system concept can be used as a power supply for low-power consumption sensors. |
