The paper deals with an efficiency calculation of an electromagnetic vibration energy harvesting system. The efficiency of this system is defined, measured, calculated and the energy harvesting model is verified. The effect of individual harvester’s parameters is observed with aim to improving design with the same volume and weight of the energy harvester. The impact of vibration energy harvesting systems has limitations in a resonance operation and a level of used mechanical vibrations. However the efficiency improvement could be useful for the wider using vibration energy harvesting systems in applications with lower level of mechanical vibrations.
