Development of a Vibration Powered Micro Generator and its Application to Harvest the Vibration Energy of the KRI KKP-811’s Engine
ABSTRACT: Vibration energy
harvesting has been receiving a considerable amount of interest as a means of
powering wireless sensors and low-power
devices. In this paper, an energy harvester is presented to convert ambient
mechanical vibration into electrical energy employing magnetoelectric
generator. The harvester uses single magnet-spring attached on the coil. When the
harvester is excited, the magnet moves relative to the coil, undergoes magnetic
field variations and produces a power output. To obtain a maximum power output,
the mass of magnet is varied. The magnetoelectric generator with various masses
of magnets was tested by a harmonic exciter with various frequencies and
amplitudes. The one with maximum power output was then applied to harvest the
ambient vibration energy of KRI KKP-811’s Engine. The results show that this
prototype can harvest maximum energy of
2μW when it is placed at the base/foundation of the engine.
