Abstract

The invention discloses an implanted neural electrode array system and a manufacturing method thereof, relating to the technical field of implanted medical appliances. The system comprises an electrode array, an outer lead and a packaging body made from medical silicon rubber materials, wherein the electrode array comprises one or multiple neural electrodes; the electrode array is fixed in the packaging body; a through hole for only enabling the neural electrodes to be exposed is formed on the packaging body; the system also comprises an embedded circuit which is sealed in the packaging body and comprises a processing chip; the neural electrodes are connected with the processing chip; and the first end of the outer lead is connected with the processing chip, and the second end of the outer lead extends to the outside of the packaging body. The system has excellent biocompatibility. Simultaneously, in the manufacturing process of the system, low-temperature sputtering and low-temperature bonding technologies are adopted, thereby overcoming the technical defect that because the heat stress of the medical silicon rubber is large, other processing materials are easy to damage.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, in particular to an implantable nerve electrode array system and a manufacturing method thereof. Background technique [0002] From the earliest discovery by Benjamin Franklin that electric current can be used to treat paralysis, to the development of Brain Computer Interface (BCI) technology into a hot spot in scientific research in recent years, neural electrodes have been used by people to study the biological nervous system for centuries. way of working and an important tool in the treatment of its dysfunction. On the one hand, it is used to collect the action electrical signals of biological neurons and send them to external electronic computer equipment for processing and analysis; on the other hand, it applies the command signals of electronic computer equipment to biological neurons to realize biological signal transmission. BCI technology based on neural electrode a...
