TRANSCUTANEOUS PHOTOVOLTAIC FEEDING OF AN IMPLANTED ELECTRONIC OR ELECTRICAL DEVICE.

摘要

System comprising: - an electronic or electrical device (2), implantable in a human or animal body, comprising a photovoltaic converter (23) for providing its power supply; and - a lighting device (1), intended to be disposed outside said human or animal body, comprising a plurality of light sources that can be turned on or off individually to effect transcutaneous illumination of said photovoltaic converter; characterized in that said lighting device comprises a controller for calculating an energy transfer efficiency between said lighting device and said photovoltaic converter, and for individually turning on or off said light sources so as to maximize said efficiency or to ensure that it is greater than a predetermined threshold.
