    摘要: The various embodiments herein provide an energy harvester which can capacitively harvest stray electric field from low-voltage AC power lines without a physical grounding connection. The energy harvester comprises an inner electrode, an outer electrode and a circuit. The inner electrode forms an inner periphery of an upper portion of a harvester housing. The outer electrode forms an inner base of a lower portion of the harvester housing to provide a local ground reference. The circuit is housed within the lower portion of the harvester housing to direct stored energy and control an energy discharge.
