1. A method for wireless power transmission, the method comprising:

  • receiving, by a transmitter, from one or more sensors, location data about a location associated with one or more objects within a transmission field of the transmitter, wherein;

    the one or more sensors include a proximity sensor configured to send the location data of the one or more objects, andthe one or more objects are associated with a maximum permissible exposure (MPE) level;

    transmitting, by the transmitter, one or more power waves to converge to form a pocket of energy at a location of an electronic device; and

    transmitting, by the transmitter, one or more power waves to converge destructively to form a null space at the location of the one or more objects, the null space having a power density level that is below the MPE level.
