A self-capacitance based remote power delivery device includes a modulating power source electrically coupled to a grounded substrate, an energy harvesting device coupled to the grounded substrate, and the substrate. The modulating power source is configured to be capacitively coupled to a self-capacitive body. The energy harvesting device configured to be capacitively coupled to the self-capacitive body, and the substrate is configured to be capacitively coupled to a portion of the self-capacitive body in direct contact with the substrate.
