Reconfigurable Filter Design for Implantable Auditory Prosthesis

摘要

Cochlear Implants (CI) are implantable electronic devices that can partially restore hearing to profoundly deaf patients by directly stimulating the patient's auditory nerve via surgically implanted electrode arrays [1]. Rather than introducing a processed acoustic signal, implants receive, process, and transmit acoustic information via electrical stimulation. A block diagram of a transcutaneous CI is shown in Fig. 1.
