    Area of Science:

    • Biomedical Engineering
    • Neuroscience
    • Otolaryngology

    Background:

    • Cochlear implants require sophisticated electrode assemblies for auditory signal transmission.
    • Transcutaneous energy and signal delivery are crucial for implantable devices.

    Purpose of the Study:

    • To describe the design and function of a novel 6- or 8-channel electrode assembly for cochlear implants.
    • To present two distinct receiver systems for transcutaneous signal and energy transfer.
    • To evaluate the electrical performance of the described system.

    Main Methods:

    • Surgical implantation of a 6- or 8-channel electrode assembly through the round window into the scala tympani.
    • Utilization of two receiver systems: a simple reed contact system and a complex hybrid technology system.
