A Synthetic Tympanic Membrane for Middle Ear Acoustic Sensor Tests of a Fully Implantable Cochlear Prosthesis

Abstract

A physical model of human Tympanic Membrane (TM), based on PDMS, as an easily accessible test platform for acoustic transducers was designed and fabricated. • A primitive ear canal simulator (TM holder) design was done using COMSOL FEA. • Vibration behavior of TM was tested with a Scanning Laser Doppler Vibrometer (SLDV). • Effect of an attached mass on the membrane was performed utilizing 32 mg and 57 mg accelerometers. • The model reproduced the basic vibrational characteristics of a human TMThe authors acknowledge European Research Council (ERC) for the financial support through FLAMENCO Project (Project No: 682756)
