Claim:
1. An ingestible device to communicate information, the ingestible device comprising: a support structure; a first material physically associated with the support structure; and a second material physically associated with the support structure at a location different from a location of the first material, wherein the second material is dissimilar from the first material and has a different electrochemical potential such that the first and second materials produce a voltage potential difference as a result of the first and second materials being in contact with an electrically conductive fluid; and a control device coupled to the first and second materials and powered by the voltage potential difference produced by the first and second materials when the first and second materials are in contact with the electrically conductive fluid, wherein the control device is configured to produce a first current signature comprising first information, which is conducted along a first current path formed by the electrically conductive fluid, the first material, and the second material, and wherein the control device is configured to produce a second current signature which is conducted along a second current path formed by the electrically conductive fluid, the first material, and the second material; wherein the first information includes programming instructions to program an implantable device.
