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.

The invention relates to a device (1) intended for detecting and/or measuring out one or more chemical compounds and comprising at least a first and a second vibrating surfaces (21), each having a resonance frequency that varies when placed in the presence of at least one chemical compound to be detected; and at least one first system (12) for actuating the first and second vibrating surfaces (21), said actuating system being suitable for vibrating the first and second vibrating surfaces (21). The first actuating system (12) is suitable for generating a first mechanical wave remote from the first and second vibrating surfaces (21). Said actuating system (12) is arranged in said device (1) such that the first mechanical wave is transmitted to the first and second vibrating surfaces (21) such as to vibrate the first and second vibrating surfaces (21). The invention also relates to a cell (10) for forming such a device (1).
摘要:
A microelectrode (2) for neural interfacing applications comprises a first substrate layer (4), a second attachment layer (6), and a third layer (8) forming the active part of the electrode (2) of which the material consists of synthetic diamond made electrically conductive by doping with atoms chosen from boron, nitrogen and phosphorus atoms. The material of the third layer (8) is a textured material that comprises a compact assembly, in the form of a brush, of tubes (26) each comprising, in the form of at least one peripheral outer layer, polycrystalline diamond made electrically conductive by doping. The tubes (26) are separated from each other at the first fixed ends (28) of same and project the free ends (30) of same away from the first and second layers (4, 6) in a direction that is substantially vertical relative to the extension plane (20) of the second layer (6). A method for producing said microelectrode is also described.
