Abstract

The invention discloses a human otolith organ solid model based on a surface symmetric electrode piezoelectric material rod. The human otolith organ solid model accurately simulates the structure andthe working mechanism of a human otolith organ. The human otolith organ solid model comprises a round-box-shaped rigid shell (8) and a communicating pipe (9), and the space between the round-box-shaped rigid shell (8) and the communicating pipe (9) is filled with liquid (7); a cylindrical flexible elastomer (5) is arranged in the rigid shell (8), a gap sealed by a flexible elastic film (4) is formed in the joint of the bottom of the rigid shell (8) and the flexible elastomer (5), the model further comprises a base (2) and surface symmetrical electrode piezoelectric material rods (11, 12, 13, 14) which are fixed to the bottom of the base (2), and a stepped structure elastic rod (3) of which the lower portion makes contact with the surface symmetrical electrode piezoelectric material rods (11, 12, 13,14). The upper part of the stepped structure elastic rod (3) penetrates through the flexible elastic film (4) and is sealed in the flexible elastic body (5).

Description

technical field [0001] The invention belongs to the technical field of human organ bionics, in particular to a human otolith organ solid model based on a surface symmetrical electrode piezoelectric material rod. 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 meas...
