This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.
