SIMULATION OF OUTER HAIR CELL ELECTROMOTILITY DUE TO FLEXOELECTRICITY
In this paper, the dynamic governing equation and electrical equation of the axial vibration of outer hair cells under external electric stimulation are discussed.The influence of two different electrical boundary conditions on electromotility mechanisms of outer hair cells due to flexoelectricity are discussed in the frequency domain.The calculation results under the voltage clamp condition show that the mechanical work output in the low frequency domain decreases with increasing membrane thickness.The fluid viscosity would restrict the end axial velocity and mechanical work output in the high frequency zone.Under the microchamber voltage condition, the mechanical work output decreases with increasing cell base voltage;and the mechanical work output is greater than the mechanical work output under the voltage clamp condition.
