In this research paper, a new technology of energy method based on stray electric field of an electric power line of India at 230 V is presented. This energy can be used for low power wireless sensor and in future it can be used in charging smart phone etc. In our research we found that energy can be harvested and stored in the storage capacitor that is connected to a cylindrical aluminum foil wrapped around a commercial insulated 230 V power line. The average current flowing into 47 μF storage capacitor is about 4.54 μA with 60 cm long cylindrical aluminum foil. It is possible to operate wireless sensor node to transmit RF data in every 42 seconds. The harvested average power is about 47 μW in this case. Since the energy can be harvested without removing insulating sheath, it is believed that the proposed harvesting technology can be applied to power the sensor nodes in wireless ubiquitous sensor network and smart grid system.
