A Review of an Implantable Middle Ear Microphone: New Floating Piezoelectric Microphone
An increasing number of (those with severe and profound sensorineural hearing loss, SSHL / PSHL) have benefited from cochlear implants (CIs). The exterior components of CIs, including the speech processing system, exterior coil, power supply component, and microphone (sensor), can be attract attention and inconvenient, may embarrass patients, can limit patients’ social activities, can cause the...
متن کاملThe frequency response of a floating piezoelectric microphone for the implantable middle ear microphone.
OBJECTIVES/HYPOTHESIS A piezoelectric sensor, floating piezoelectric microphone, driven by acoustic vibration of the ossicles, is one possible design for a microphone for a totally implantable cochlear implant. The purpose of the article was to study the frequency response of the floating piezoelectric microphone and to identify the ideal feasible position in the ossicular chain. STUDY DESIGN...
متن کاملFeasible pickup from intact ossicular chain with floating piezoelectric microphone
OBJECTIVES Many microphones have been developed to meet with the implantable requirement of totally implantable cochlear implant (TICI). However, a biocompatible one without destroying the intactness of the ossicular chain still remains under investigation. Such an implantable floating piezoelectric microphone (FPM) has been manufactured and shows an efficient electroacoustic performance in vit...
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 کاملConcept and Evaluation of a New Piezoelectric Transducer for an Implantable Middle Ear Hearing Device
Implantable middle ear hearing devices (IMEHDs) have been developed as a new technology to overcome the limitations of conventional hearing aids. The piezoelectric cantilever transducers currently used in the IMEHDs have the advantages of low power consumption and ease of fabrication, but generate less high-frequency output. To address this problem, we proposed and designed a new piezoelectric ...
