| titleOfInvention | SYSTEM OF FLEXIBLE ELECTROSES, ATTACHABLE TO NERVES, FOR PULSE DETECTION / FORMATION AND THEIR MANUFACTURING TECHNOLOGY |
| abstract | The invention relates to a system of flexible electrodes that can be attached to nerve bundles to pick up or transmit the potential difference recorded thereon on the transmission / reception of a stimulus. The system according to the invention consists of two pairs of electrodes (202 and 203) with the role of collecting and / or transmitting pulses and a reference electrode (204) with the role of providing the potential reference for the input amplifier thus allowing the collection of both alternatives. of the pulse (104), the electrodes (202, 203 and 204) being made in the form of thin films from superimposed layers of Cr - Au resulting in a conductive layer with a thickness of 20 nm Cr and 200 nm Au. The manufacturing method according to the invention consists in fixing a 0.2 mm thick Kapton foil (402) on a glass support (401) and cleaning the Kapton foil (402) by oxygen plasma corrosion, over which the mask is deposited. (403) in order to execute the photolithographic process preceding the metal deposition, and the whole assembly is introduced in the magnetron sputtering installation where the first metal layer of Cr with a thickness of 20 nm is deposited followed by the deposition of the final layer of Au with a thickness of 200 nm , the whole assembly being subjected to a chemical detachment operation of the metal area around the electrodes by introduction for 30 min. in an ultrasonic bath using acetone heated to 50 ° C, and to isolate the conductive pathways that come into contact with the tissue around the electrodes, they were coated with a layer of polydimethyl siloxane PDMS by display at 1000 rpm using a mask (405) covering the paths that are not deposited with PDMS and leave the windows open for PDMS deposition, the product obtained is subjected to a heat treatment at 60 ° C in an atmosphere of N2 for 120 min., After which the holes (205) of suture and remove the edges by laser cutting. |
