Abstract
A device and system for power transmission. A power transmission system comprises an RF power source coupled to one or more emitters producing a field which transfers power to one or more sinks. A sink comprises one or more collectors coupled to a resonator, which couples RF power from the collectors and resonator to harvesting electronics which convert the RF power to direct current to power a load. Emitters coupled to the source produce a field which is harvested by the sink and converted to DC for a load. Emitters and collectors may be capacitively coupled, or coupled through a conductive path. Coupling may include a ground path. Charge mobility elements may be used with emitters and/or collectors.
