Abstract
A device and system for data transmission. A data 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. Data modulated on the RF source is transferred to the harvesting electronics in the sink where the modulated RF is decoded into data. Known modulation techniques may be used. Power and data may be provided by the source to the sinks. Load modulation may be used by a sink to transfer data to the source or to other sinks. 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.
