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

  • generating, by a sound wave (SW) circuit embedded within a transmitter coupled to a power source, power SW signals;

    generating communication signals from a communication circuit embedded within the transmitter;

    controlling the generated power SW signals and the communication signals with a digital signal processor;

    transmitting the power SW signals through at least two transducers and the communications signals through a communication antenna, the at least two transducers electrically connected to the SW circuit and the communication antenna electrically connected to one or more communication circuits within the transmitter,wherein the power SW signals are transmitted to converge to form controlled constructive interference in 3-D space at a receiver with an antenna connected to the electronic medical device or sensor, andwherein the receiver is configured convert energy at the controlled constructive interference into a DC voltage for charging or powering the medical device or sensor; and

    receiving, by the communication antenna, the communication signals from the receiver, wherein the communications signals generated from the receiver indicate a location of the receiver, and power requirements of the electronic medical device or sensor, andwherein the communications signals indicate an optimum time and location for converging the power SW signals to form the controlled constructive interference at the receiver.
