Abstract

In this research, we developed numerically a Prototype Auditory Membrane (PAM)for a fully implantable
and self contained artificial cochlea. Cochleae are one of the important organs for hearing in the human
and animals. Material of the prototype and implant of PAM are made of Polyvinylidene fluoride (PVDF)Kureha,
Japan
which
is
fabricated
using
MEMS
and
thin
film
technologies.
Another
important
thing
in
the
characteristic
of the PAM is not only convert the acoustic wave into electric signal but also the frequency
selectivity. The thickness, Young’s modulus and density of the PAM are 40 μm, 4 GPa, and 1.79  10
kg/m
3
, respectively. The shape and dimension of the PAM is trapezoidal with the width is linearly changed
from 2.0 to 4.0 mm with the length are 30 mm. Numerically, we develop the model of PAM is based on
commercial CFD software, Fluent 6.3.26 and Gambit 2.4.6. The geometry model of the PAM consists of
one-sided blocks of quadrilateral elements for 2D model and tetrahedral elements for 3 D model
respectively. In this study we set the flow as laminar and carried out using unsteady time dependent
calculation. The results show that the frequency selectivity of the membrane is detected on the membrane
surface
