ABSTRACT:
A bi-directional galvanic conduction transdermal communication system is disclosed. The system includes an internal communication device implanted inside the body of a patient and an external communication device. The external communication device includes an external transmitter which transmits a carrier signal into the body of the patient during communication from the internal communication device to the external communication device. The carrier signal causes galvanic conduction to occur through the skin of the patient. The internal communication device includes an internal modulator that modulates the carrier signal with information stored in the internal communication device by selectively controlling the level of galvanic conduction that occurs through the skin of the patient. During external to internal communication, an external modulator modulates the carrier signal with information contained in the external communication device. Accordingly, the majority of the energy required for communication between the external and internal communication devices, regardless of the direction, is provided by the external communication device.
