Mastication noise reduction method for fully implantable hearing aid using piezo-electric sensor

Ultraminiature encapsulated accelerometers as a fully implantable sensor for implantable hearing aids.

Experiments were conducted to evaluate a silicon accelerometer as an implantable sound sensor for implantable hearing aids. The main motivation of this study is to find an alternative sound sensor that is implantable inside the body, yet does not suffer from the signal attenuation from the body. The merit of the accelerometer sensor as a sound sensor will be that it will utilize the natural mec...

Obstructive Sleep Apnea Screening Using a Piezo-Electric Sensor

In this study, we propose a novel method for obstructive sleep apnea (OSA) detection using a piezo-electric sensor. OSA is a relatively common sleep disorder. However, more than 80% of OSA patients remain undiagnosed. We investigated the feasibility of OSA assessment using a single-channel physiological signal to simplify the OSA screening. We detected both snoring and heartbeat information by ...

Optimization 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...

Optimization of MEMS Based Capacitive Accelerometer for Fully Implantable Hearing Aid Application

INTRODUCTION: According to the 2015 estimates of WHO, 278 million people have disabling hearing impairment. In India, 63 million people suffer from significant auditory loss. The majority of all hearing loss is sensorineural loss which refers to hair cells damage in cochlea, a snail like structure inside the inner ear which connects to the auditory nerve in the brain. The use of conventional he...
