1. A method for wireless transmission of power to an electronic medical device or a sensor, the method comprising:

  • generating pocket forming power radio frequency (RF) signals from a RF circuit embedded within a transmitter connected to a power source;

    generating communication signals from a communication circuit embedded within the transmitter, wherein the transmitter comprises a communication antenna configured to transmit and receive communications signals to and from a receiver coupled to an electronic device, wherein the electronic device is a medical device or a sensor;

    controlling the generated power RF signals and the communication signals with a digital signal processor coupled to the transmitter;

    transmitting the power RF signals by at least two antennas electrically connected to the RF circuit within the transmitter;

    wherein an antenna of the receiver is configured to capture energy from the pocket of energy produced by the pocket-forming power RF signals in converging in 3-D space, and wherein the receiver is configured to convert the energy into a DC voltage for charging or powering the medical device or the sensor coupled to the receiver; and

    transmitting, by the communication circuit of the transmitter, instructions in the communication signals to the receiver to generate location data, power requirements, and timing data; and

    receiving, by the communication circuit, the communications signals from the receiver, wherein the communication signals received from the receiver provide an optimum time and location data indicating the location associated with the electronic device coupled to the receiver for converging the power RF signals to form the pocket of energy in 3-D space at the location.
