摘要:
The invention relates to a method for manufacturing an intraocular retinal implant including a flexible plate made of insulating material, one face of which is provided with a plurality of electrodes made of doped diamond connected to interconnection lines. Said method includes providing a mold capable of supporting the growth of a layer of doped diamond, said mold comprising, on one of the faces thereof, a set of elements which are all depressed or all projecting with respect to the surface of said face, and which constitute a 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 the space occupied by the elements of the cavity; forming a first insulating layer on the face of the mold comprising the cavity; producing the interconnection lines by depositing an electrically conductive material at least in the spaces not covered by the first insulating layer; forming a second insulating layer on the face of the mold including the cavity, said second layer covering the interconnection lines, the first and second insulating layers forming the flexible plate of the implant; and removing the mold.
摘要:
An electrode comprising a biocompatible chemically oxygen terminated or H-terminated carbon-based material, the surface of which is substantially free of any peptide coating and promotes the growth or at least the direct interfacing of adult neurons on said material without substantially promoting the growth and direct interfacing of glial cells on said material, said carbon-based material having an electrical conductivity of at least about 0.01S/cm, in particular 1S/cm, said material being in particular selected from the group consisting of nanocrystalline diamond which is doped by either boron, phosphorus or nitrogen, to become a semiconductor, or graphene, nanotubes, or nanotubes on diamond. Further disclosed is a use of said electrode as well as a process of preparation of said electrode.

Semiconductor substrate (100) comprising at least: a doped-diamond-based film (106) with a thickness equal to or greater than 10µm; a layer (102) based on at least one semiconductor or a multilayer stack that includes the semiconductor-based layer; and an intrinsic-diamond-based film (104) placed on the doped-diamond-based film, i.e. between the doped-diamond-based film and the semiconductor-based layer.
摘要:
The invention relates to a collector-electrode assembly which can be integrated into an electrical energy storage device. The assembly comprises a stack formed by a highly conductive collector comprising a substrate (8) and an electrode including a nano-structured active layer (12) made up of a network of nano-structures. The collector-electrode assembly is characterized in that the nano-structured active layer (12) is covered with a layer (14) comprising diamond nanoparticles (20). The invention also relates to an associated energy storage device and an associated production method.
