The driver circuit is configured to alter conductance. A partial power source is coupled to the control device and is configured to provide a voltage potential difference to the control device and the driver circuit as a result of the partial power source being in contact with a conductive fluid. The partial power source includes a first material electrically coupled to the control device and a second material electrically coupled to the control device and electrically isolated from the first material. An inductor is coupled to the driver circuit. The driver circuit is configured to develop a current through the inductor. The magnitude of the current developed through the inductor is varied to produce an encoded signal that is remotely detectable by a receiver. Receivers to receive and decode also are disclosed.
