A commutator including a commutator main body having a plurality of commutator pieces and a short-circuit member having a short-circuit conductor for short-circuiting commutator pieces. The method enables separating a solid layer from a supply substrate and optionally transferring the solid layer onto a target substrate. In terms of the Open Systems Interconnect layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions.
