abstract
The cochlea, in the mammalian inner ear, transduces acoustic waves into electrical signals that are transmitted to the brain. One of the critical functions of the cochlea is its biological nonlinear behavior that amplifies faint sounds and compresses high sound levels. Previously, authors mimicked the aforementioned nonlinear characteristics in piezoelectric augmented structural cantilevers through nonlinear feedback controllers. The present effort is a continuation of the previous studies in the development of micro-electro-mechanical system (MEMS) scale artificial hair cells (AHCs).
