TRANSCUTANEOUS PHOTOVOLTAIC SUPPLY OF AN IMPLANTED ELECTRONIC OR ELECTRICAL DEVICE

摘要

The invention relates to a system comprising: an electronic or electrical device (2) that can be implanted in a human or animal body, comprising a photovoltaic converter (23) for providing the electrical energy supply of said device; and an illuminating device (1) to be positioned outside the human or animal body, comprising a plurality of light sources that can be turned on or off individually in order to perform a transcutaneous illumination of the photovoltaic converter; characterised in that said illuminating device comprises a controller for calculating an energy transfer efficiency between said illuminating device and said photovoltaic converter, and for turning said light sources on or off individually in such a way as to maximise said efficiency or ensure that it is above a pre-determined threshold.
