Abstract: A wireless power transmitter system includes: a power delivery structure comprising power transmitting elements (power transmitting elements), each of which is configured to induce a field, and configured to adapt to an exterior shape of an entity that contains a receiver; a power circuit configured to provide power to the power transmitting elements selectively; and a controller configured to: determine an electrical characteristic, other than power transfer to the receiver, associated with actuating at least one of the power transmitting elements; determine at least one power transmitting element subset, based on the electrical characteristic, containing less than all, and at least one, of the power transmitting elements; select, based on power transferred to the receiver, one or more charging power transmitting elements to use to charge the receiver wirelessly; and cause the power circuit to provide power to the one or more charging power transmitting elements.
