Abstract
Ingestible event markers having high reliability are provided. Aspects of the ingestible event markers include a support, a control circuit, a first electrochemical material, a second electrochemical material and a membrane. In addition, the ingestible event markers may include one or more components that impart high reliability to the ingestible event marker. Further, the ingestible event markers may include an active agent. In some aspects, the active agent, such as a pharmaceutically active agent or a diagnostic agent may be associated with the membrane.

21. An ingestible event marker comprising:
-
a support; a control circuit in contact with the support to control the event marker; a first electrochemical material in contact with the support and electrically coupled to the control circuit; a second electrochemical material electrically coupled to the control circuit and in contact with the support at a location different from the location of the first material to electrically isolate the first and second electrochemical materials from each other, wherein the first electrochemical material is dissimilar from the second electrochemical material; and a membrane physically associated with the support and positioned between the first electrochemical material and the second electrochemical material, wherein the membrane comprises an electrically insulative material, and wherein the first electrochemical material, the second electrochemical material, and the membrane are configured to produce a dipole having a predefined dipole length based on the membrane; and wherein the control circuit is configured to generate an electrically conductive signal along a current path that employs a body as an electrically conductive medium upon the application of a voltage potential to the control circuit. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
