1. A wireless charging transmitter comprising:

  • one or more sensors configured to;

    detect a living being in proximity to the wireless charging transmitter; and

    generate sensor data based on detecting the living being;

    an array of antennas configured to transmit power waves to a receiver device; and

    a surface layer that is adjacent to the array of antennas,wherein;

    the transmitted power waves converge to form a constructive interference pattern at a non-zero distance from the surface layer, the non-zero distance being based at least in part on the sensor data;

    phases and amplitudes of the transmitted power waves are determined based, at least in part, on the sensor data; and

    the wireless charging transmitter is further configured to lower a power level of the transmitted power waves in response to the one or more sensors detecting the living being.
