1. A method for wireless power transmission comprising:

  • transmitting, by a transmitter, power waves that converge in a three dimensional space to form one or more first pockets of energy at a predetermined location for receiving by an antenna element of a receiver, wherein the receiver is configured to harvest power from the one or more first pockets of energy at the predetermined location;

    acquiring, by at least one sensor in communication with the transmitter, data indicating presence of a living being or a sensitive object, wherein the data indicating the presence of the living being or the sensitive object indicates a distance of the living being or the sensitive object from the at least one sensor;

    obtaining, by the transmitter, information relating to a location of the living being or the sensitive object based upon the data indicating the presence of the living being or the sensitive object; and

    determining, by the transmitter, whether to adjust a power level of the power waves that converge in the three dimensional space to form the one or more first pockets of energy at the predetermined location in response to the information relating to the location of the living being or the sensitive object.
