Abstract: A method for manufacturing an intraocular retinal implant including: providing a mold capable of supporting growth of a layer of doped diamond, the mold including, on one face, elements all depressed or all projecting with respect to the surface of the face, and constituting a pattern cavity for the electrodes of the implant which it is desired to obtain; producing the doped diamond electrodes by growing a layer of doped diamond in all or part of a space occupied by the pattern cavity elements; forming a first insulating layer on the face of the mold including the pattern cavity; producing interconnection lines by depositing an electrically conductive material at least in spaces not covered by the first insulating layer; forming a second insulating layer on the mold face including the pattern cavity, the second layer covering the interconnection lines, the first and second insulating layers forming a flexible plate of the implant; removing the mold.

Abstract: The invention relates to an implant which includes, in order to electrically stimulate a nerve structure, in particular the retina, an electrically insulating substrate (1), a array of recesses (2) formed in an upper surface of the substrate, stimulation electrodes (3) arranged at the bottom of the recesses, and an electrically conductive layer forming a ground plane (4) at the upper portion of the recesses. The sizes of the recesses and of the electrodes of the implant are such that the spatial selectivity of the stimulation current applied to the nerve structure is maximized.

Abstract: The invention relates to a sensing means for a contact lens used in a physiological parameter measuring system comprising one or two contact lenses, wherein to improve the comfort of wear for a patient each contact lens comprises an antenna and a purely passive sensing means.

Abstract: The present invention relates to an electromagnetic signal power limiter and its design method. The power limiter for an electromagnetic signal includes at least one transmission line for the signal. The transmission line is made up of a number of passive micro-diodes with ballistic electron transport. The micro-diodes are distributed on the transmission line, and are implemented in a controlled atmosphere. The invention applies notably to radiofrequency or hyperfrequency waves received by detection and communication devices.
