Background technique [0004] Many medical devices have been developed to help people who have been born or acquired with a loss of a specific function. As such medical devices, human implants including nerve assist devices have also been developed. [0005] As one of the implanted devices in the human body, the cochlear implant system uses electric current to stimulate the auditory nerve of a person with auditory function nerves to help people perceive sound. The cochlear implant system is recognized as the most effect...

Problems solved by technology

[0010] However, conventional electrodes have problems of increased cost and time, and decreased yield because platinum electrodes and wires are manually resistance-welded and silicon-molded

Also, since electrodes and wires are resistance welded manually, there is a limit in increasing the number of electrodes
