Biomechanical study on the sensorial epithelium of otolithic organs for creating a biomimetic sensor.
This paper presents a biomechanical model of the sensorial cells in otolithic organs and a design of a 3D device that imitates the biological system. Starting from anatomical and physiological data, mechanical and structural parameters have been identified and a mechanical model has been formulated, by considering the cilia and kinocilium as a interconnected structure. The mechanical model was used to simulate the behavior of the system under known conditions. Furthermore, the behavior of a proximal link to the kinocilium were investigated for a better comprehension regarding the polymeric materials that could be used to model and manufacture the biological organs. The results obtained from the models were used to design a biomimetic organ.
