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 also measure the conditions of the environment surrounding the system.

9. A device to communicate with a receiver, the device comprising:
-
a support structure made of semi-conductor material, wherein the support structure includes a power storage unit to store power; a partial power source comprising; a first material associated with the support structure; and a second material insulated from the first material and associated with the support structure, wherein the first and second materials are selected to represent a voltage potential difference when in contact with a conducting fluid; a control module associated with the support structure and electrically connected to the power storage unit as well as the first material and the second material, wherein the control module alters the conductance of the device to change the device'"'"'s current signature when the device is in contact with the conducting fluid and thereby encode information in the current signature that is detectable by the receiver; and a non-conducting membrane secured around the support structure and positioned relative to the first and second materials to facilitate extension of the current path between the first material and the second material, wherein the power storage unit powers the control module while the partial power source is below a threshold level. - View Dependent Claims (10, 11, 12, 13)

15. A device to communicate with an external device and a receiver in contact with a user, the device comprising:
-
a support structure made of semi-conductor material that stores power; a partial power source comprising; a first material deposited on the support structure; and a second material insulated from the first material and deposited on the support structure, wherein the first and second materials are selected to include a voltage difference when in contact with a conducting fluid; a control module secured to the support structure and electrically connected to the first material and the second material for controlling the conductance between the first material and the second material such that changes in conductance correspond to changes the device'"'"'s current signature and the changes in the current signature represent information in the current signature and the information is detectable by the receiver; a communication module secured to the support structure to communicate with the external device and coupled to the control module and the stored power in the support structure, wherein the communication module at least either sends or receives information; a non-conducting membrane secured to the support structure and positioned relative to the first material and the second material to extend the electrical path between the first material and the second material; and a strip positioned on the membrane and electrically coupled to the communication module, wherein the strip at least does one of communicate information and receive power. - View Dependent Claims (16, 17, 18, 19)
