Development and New Trends and Challenges in Cochlear Implant Technology
Abstract：1 Development of Cochlear Implant Technology. Two centuries ago, the Italian scientist Alessandro Volta proved that electrical stimulation could elicit auditory perception. In 1957, Djourno and Eyries from France successfully performed auditory nerve electrical stimulation on a deaf person for the first time. In 1961, William F. House implanted a single-channel electrode device into the cochlea for the first time, establishing the feasibility of cochlear implants. In 1972, Graham Clark developed a multi-channel device, which not only allowed deaf individuals to perceive complex environmental sounds but also significantly improved speech recognition ability [1]. In 1984, multi-channel cochlear implants were approved by the U.S. Food and Drug Administration, marking their official entry into clinical use.
