An Intracochlear Pressure Sensor as a Microphone for a Fully Implantable Cochlear Implant.
OBJECTIVE To validate an intracochlear piezoelectric sensor for its ability to detect intracochlear pressure and function as a microphone for a fully implantable cochlear implant. METHODS A polyvinylidene fluoride (PVDF) piezoelectric pressure sensor was inserted into a human fresh cadaveric round window at varying depths. An external sound pressure stimulus was applied to the external audito...
متن کاملOptimization of MEMS Capacitive Accelerometer as Fully Implantable Middle Ear Microphone for Hearing Aid
This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis is done using COMSOL Multiphysics. The maximum applied acceleration was considered 1g. Human temporal bones a...
متن کاملA MEMS Capacitive Accelerometer Design as Middle Ear Microphone Based on Ossicular Chain Micromechanic Characterization at Umbo for Fully Implantable Cochlear Prosthesis
An accelerometer attached to an umbo is proposed as a middle ear microphone for future fully implantable cochlear prostheses. The micromechanic characterization of cadaveric temporal bones indicates that a miniature accelerometer with a sensing resolution of 35 µg/ Hz, a bandwidth of 8 kHz, and a packaged weight less than 20 mg is required for detecting normal conversation, and that the acceler...
متن کاملA New Trans-Tympanic Microphone Approach for Fully Implantable Hearing Devices
Fully implantable hearing devices (FIHDs) have been developed as a new technology to overcome the disadvantages of conventional acoustic hearing aids. The implantable microphones currently used in FIHDs, however, have difficulty achieving high sensitivity to environmental sounds, low sensitivity to body noise, and ease of implantation. In general, implantable microphones may be placed under the...
متن کاملImplications for Cochlear Implants
Amplitude envelope co-varies with F0 in Mandarin lexical tones. It can cue lexical tone perception in a tone language such as Mandarin which uses different pitch contours for phonemic contrasts. The current study investigated whether amplitude envelope could also aid the perception of lexical tones in a language such as Cantonese which uses both pitch contour and relative pitch height for phone...
