摘要 |
A physiological function assisting device 1 is embedded in the body, and is provided with a transmitter 11 and receiver 12 for communicating with an external controller 2 . External controller 2 controls embedded physiological function assisting device 1 from the outside. External controller 2 is provided with a transmitter 21 and receiver 22 for communicating with physiological function assisting device 1 . Transmitters 11,21 modulate the plane of polarization of laser light, and emit the result as a transmission signal. Receivers 12,22 selectively receive light of a specific polarization state. Receivers 12,22 respectively 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.
