Intelligent wireless sensors are more and more common in many branches of technical diagnostics. The need for knowing and record measured quantities is keep rising. This concern especially passive households, in office buildings with many air condition units but also in industry there is need for made simple interventions on many places. If there is no sufficient electric power distribution, there is than issue concerning how to supply many wireless sensors. Because of mentioned issues, the favorite powering technology it start to be an Energy Harvesting. Standard methods are capable to supply only mW of electric energy from surrounding free energies, which is so low. Our system is capable to supply tenths or hundreds of mW of electric power to the load. As an input serves standard Peltier Cell , which is commonly used to cool electronic equipment, or single solar cell or other voltage source from 0,1 V – 0,5 V.
