Abstract
The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can be used in a variety of different applications, including as components of ingestible identifiers, such as may be found in ingestible event markers, e.g., pharma-informatics enabled pharmaceutical compositions.
