ARTIFICIAL VESTIBULAR ORGAN SYSTEM

摘要

The present invention relates to an artificial vestibular organ system comprising: an artificial semicircular canal; a liquid with which the artificial semicircular canal is filled; an artificial cilia means detecting movement of the liquid inside the artificial semicircular canal; a signal conversion unit converting a signal generated in the artificial cilia means into a bio-stimulation signal; a bio-stimulation pulse generation unit transmitting the bio-stimulation signal converted in the signal conversion unit to ampulla; and a power supply unit supplying power to each component. The artificial cilia means may be performed in a pressure detective type detecting pressure according to flow of a liquid or a rate detective type detecting a flow rate according to flow of a liquid. The artificial cilia means in the pressure detective type may be performed in a flex sensor method using a bending element, a piezo sensor method using a piezo element, and an FSR sensor method using a polymer film. The artificial cilia means in the rate detective type may be performed by including a rotary blade rotated according to flow of a liquid, and a speed measuring device measuring a rotary rate of the rotary blade. The speed measuring device may include a hall sensor or an optical encoder. According to the present invention, the artificial vestibular organ system is applied to a human body with a damaged vestibular organ to serve a role of a semicircular canals, thereby helping rehabilitation of persons having difficulty in living due to a damage to a vestibular organ.
