Human otolith organ solid model based on liquid core bionic cells

Abstract

The invention discloses a human otolith organ solid model based on liquid core bionic cells. The human otolith organ solid model can accurately simulate the structure and the working mechanism of a human otolith organ. The human otolith organ solid model comprises a round-box-shaped rigid shell body (8) and a communicating pipe (9), wherein the space between the round-box-shaped rigid shell body (8) and the communicating pipe (9) is filled with liquid (7), a cylindrical flexible elastic body (5) is arranged in the rigid shell body (8), a gap sealed by a flexible elastic film (4) is formed in the bottom part, a base (3) is arranged on the lower part, the bottom part of the base (3) is provided with first to fourth liquid core organic piezoelectric material spheres (11, 12, 13 and 14) and anelastic rod (2) of a step structure, the upper end of the elastic rod (2) of the step structure penetrates through the flexible elastic film (4) and is sealed in the flexible elastic body (5), the lower end of the stepped structure elastic rod (2) is fixedly connected to the bottom part of the base (3), the first to fourth liquid core organic piezoelectric material spheres (11, 12, 13 and 14) areevenly distributed in the periphery of the elastic rod (2) of the step structure, and the first to fourth liquid core organic piezoelectric material spheres (11, 12, 13 and 14) are respectively in contact with the elastic rods (2) of the step structure.

Description

technical field [0001] The invention belongs to the technical field of human organ bionics, in particular to a solid model of human otolith organs based on liquid core bionic cells. Background technique [0002] The otolith organs in the vestibular system of the human body, including the utricle and the sac, can sense the linear acceleration of the human head, and are used to maintain body balance and stable vision. They are important sensory organs in the human form. Due to its small size, complex structure, and hidden in the skull, it is difficult to directly measure the mechanical response inside the otolith organ through existing technical means. According to the real structure of human otolith organs, artificial materials (or devices) are used to replace corresponding biological tissues, and the physical model of human otolith organs can be designed and prepared, so that the working mechanism of human otolith organs can be observed and measured more realistically, and t...

AI Technical Summary

Problems solved by technology

Therefore, the Chinese invention patent "linear acceleration sensor imitating the structure of otolith organs" is different from the structure of human otolith organs. The working principle of sensing linear acceleration is completely different, and its biomechanical characteristics are also very different. It cannot completely imitate human otolith organs.
