Fluid-structure Traveling Wave Filters Based on the Mammalian Cochlea
نویسندگان
چکیده
Micromachined fluid-structure systems capable of acoustic sensing and mechanical frequency analysis are demonstrated. These systems act as passive mechanical acoustic filters. A capacitive sensing scheme is incorporated into the structure to produce 32 channels of filtered output, each sensitive to a particular frequency band. Inspiration for the design is taken from the structure of the mammalian cochlea.

Microengineered hydromechanical cochlear model.
Micromachined fluid-filled variable impedance waveguides intended to mimic the mechanics of the passive mammalian cochlea have been fabricated and experimentally examined. The structures were microfabricated with dimensions similar to those of the biological system. Experimental tests demonstrate acoustically excited traveling fluid-structure waves with phase accumulations between 1.5 and 3 pi ...
متن کاملLaser amplification with a twist: traveling-wave propagation and gain functions from throughout the cochlea.
Except at the handful of sites explored by the inverse method, the characteristics-indeed, the very existence-of traveling-wave amplification in the mammalian cochlea remain largely unknown. Uncertainties are especially pronounced in the apex, where mechanical and electrical measurements lack the independent controls necessary for assessing damage to the preparation. At a functional level, the ...
متن کاملFully Distributed Modeling, Analysis and Simulation of an Improved Non-Uniform Traveling Wave Structure
Modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. Knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. In this paper, a lossy transmission line model of traveling wave switch (TWSW) i...
متن کاملTraveling Wave Solutions of 3D Fractionalized MHD Newtonian Fluid in Porous Medium with Heat Transfer
In the present paper, we get exact solutions of Magnetohydrodynamic (MHD) of the fractionalized three-dimensional flow of Newtonian fluid with porous and heat transfer through the traveling wave parameter. The governing equations are produced dependent on established Navier-stokes equations which can be diminished to ordinary differential equation by wave parameter ξ=ax+by+nz+Utα/Γ(α...
متن کاملLongitudinally propagating traveling waves of the mammalian tectorial membrane.
Sound-evoked vibrations transmitted into the mammalian cochlea produce traveling waves that provide the mechanical tuning necessary for spectral decomposition of sound. These traveling waves of motion that have been observed to propagate longitudinally along the basilar membrane (BM) ultimately stimulate the mechano-sensory receptors. The tectorial membrane (TM) plays a key role in this process...
