Abstract:
1. An ingestible device comprising: a support; circuitry associated with the support; a first material electrically coupled to the circuitry and associated with the support; and a second material electrically coupled to the circuitry and associated with the support, wherein the first material is electrically isolated from the second material, wherein the first and second materials are selected to provide a voltage potential difference when in contact with an electrically conductive fluid, and wherein the circuitry is configured to modulate current flow through the electrically conductive fluid to generate an encoded monophasic signal which is conductively transmitted to a remote receiver; and wherein the circuitry comprises a switch; and wherein the circuitry is configured such that when the switch is closed, a current is produced between the first material and the second material.
