The present invention provides a wireless receiver with the multi-channel or the single-channel. A liquid cleaning chemical is provided in contact with a first side of the membranes. The magnets of the driven mechanism are rotated by the magnets of the driving mechanism through magnetic interaction. Connections between ports of desired components are also defined. The replacement channel material is formed to include a gradient in which the upper portion of the replacement channel material has a greater dopant concentration than the lower portion of replacement channel material.
