APPARATUS FOR STRAY ELECTRIC FIELD ENERGY HARVESTING AND SUPPLYING ELECTRIC POWER OF SENSOR NETWORK

摘要

PURPOSE: A stray electric field energy harvesting device and a power supply device of a sensor network based on a stray electric field energy harvesting are provided to supply power to a wireless sensor node by harvesting electric field energy. CONSTITUTION: A conductor part(110) surrounds the outside of a power line(100) and occupies a preset area of the insulated power line. A harvesting circuit unit(150) rectifies a voltage generated by a stray capacity and stores the rectified voltage. The stray capacity is generated between the power line and the conductor part.
