Experimental exploration of magnet motion effect on electromagnetic energy harvesting

Energy harvesting systems for low power devices are becoming essential for different applications, such as wireless sensors, IoT devices, and autonomous systems. This study is about the exploration of the electrical energy harvested by electromagnetic effect, utilizing a mobile magnet into an electric coil. The magnet is mounted on a vibration exciter to command its motion. The motion is of different amplitudes and frequencies, using an amplitude amplifier and a frequency regulator. The magnet motion was found of a determinant effect on electromagnetic energy harvesting.
