<p>The present invention relates to a system, implantable in the body and enabling a piece of information to be transferred by light modulation through the skin and made visible on the surface. For example, the system is placed under the skin (1) of the wrist, between the forearm (2) and the hand (3), and the system has an electroluminescent diode network (6) emitting a light, the essential portion of the spectral distribution of the emitted power of which is 620 to 660 nm (red) and the brightness of which is at least equal to 100 mcd for a skin thickness of less than 5 mm, so as to make a piece of information, consisting of the points of light, appear on the surface of the skin.</p> |
