The need of energy increases in industrial advancement. To meet the high energy demands with limited natural resources it is desirable to develop energy harvesting systems. This thesis deals with the design of a similar energy efficient system for sensors in production machines. The basic motivation of the system application is to avoid the use of batteries. The batteries need to be replaced after a period of time whereas an energy harvesting system produces its own electrical energy by converting available forms of energies into useful electrical energy for example solar, thermal or vibration energy of the machines into useful electrical energy.
