An electrode stimulation delivery system is described having a unit and a network of wireless remote electrodes configured for implantation within a plurality of spaced apart locations in the tissue, e.g. myocardium, of a patient. The control unit is configured to be positioned at or subcutaneous to the patient's skin, and includes a processor, an antenna configured for delivering RF energy in proximity to the plurality of wireless remote electrodes, and programming executable on the processor for wirelessly communicating to the network of wireless remote electrodes via the delivered RF energy to individually control pacing of the plurality of wireless remote electrodes. Each of the plurality of wireless remote electrodes comprises a metamaterial-based biomimetic harvesting antenna comprising a Van Atta array zero-phase transmission lines to receive the RF energy to power activation of the plurality of wireless remote electrodes.
