We present the design and development of a tympanic membrane sensor for a totally implantable cochlear implant or hearing aid system. The sensor employs a fiber-optic lever which is hermetically sealed in a biocompatible cartridge and implanted in the middle ear cavity. The sensor prototype has been designed, constructed and tested in cats. In addition, the implantation procedure of the device has also been studied using human temporal bones.
