Abstract: As the most successful neural prosthesis, cochlear implants have provided partial hearing to more than 120000 persons worldwide. First, the cochlear implants are system designed and specifications are laid out. Second, the design goals, principles, and methods of subsystem components are identified from the external speech processor and radio frequency transmission link to the internal receiver, stimulator, and electrode arrays. Third, the system integration and functional evaluation are presented with respect to safety, reliability, and challenges facing the present and future cochlear implant designers and users. Finally, issues beyond cochlear implants are discussed to address treatment option for the entire spectrum of hearing impairment as well as to use the cochlear implant as a model to design and evaluate other similar neural prosthesis such as vestibular and retinal implants.
