ABSTRACT:
A physiological function assisting device1is embedded in the body, and is provided with a transmitter11and receiver12for communicating with an external controller2. External controller2controls embedded physiological function assisting device1from the outside. External controller2is provided with a transmitter21and receiver22for communicating with physiological function assisting device1. Transmitters11,21modulate the plane of polarization of laser light, and emit the result as a transmission signal. Receivers12,22selectively receive light of a specific polarization state. Receivers12,22respectively output electric signals corresponding to the polarization state (polarization angle or ellipticity) of the received light. As a result, full duplex communications between a strongly dispersing medium like the human body and the outside is possible, while the power consumed by the internal device can be reduced.
