PERFORMANCE ANALYSIS OF ELECTROMAGNETIC VIBRATION ENERGY HARVESTING DUE TO DIFFERENT VIBRATION SOURCES

As industry requires more real-time monitoring and interconnected systems, the need for wireless sensors will increase. Vibration Energy Harvesting (VEH) has played an important role as an alternative energy source to provide power to wireless sensors. In this paper we report the analysis of an electromagnetic energy harvester driven by vibrating plate. An experimental method where energy sources originating from vibrating mechanical machines were used. Mechanical machines such as milling machines, dynamic rotors, and four-stroke engines were implemented to prove the performance of the device. where the output signal from the vibration source is measured using a CF-3600 FFT analyzer, while the output signal from the electromagnet is measured using an oscilloscope (Hantek 6022BE). This paper has discussed several sources of vibration originating from industrial equipment with a vibration source frequency of around 10 to 100 Hz. The findings show that the voltage produced by an electromagnetic energy harvester is 130 mV, 120 mV, and 30 mV on a milling machine, dynamic rotor, and four-stroke engine. Additionally, the results contribute to the optimization of vibration energy harvesting parameters, facilitating the maximization of energy extraction in diverse applications.
