在本文中，我们研究触觉机械感受器之一的触觉小体的螺旋神经轴突的作用。示出了用于检测弹性皮肤的机械变形的盘绕结构的两个性质。首先，盘绕结构具有将弹性蒙皮的剪切变形和拉伸变形转换为盘绕线的表面的拉伸变形和剪切变形的特性。从本质上讲，拉伸和剪切变形是由螺旋结构转置的。因此，线圈的线的表面上的换能器可以分别检测弹性皮肤的拉伸和剪切变形。其次，线圈结构的阻抗远小于线圈本身的线路阻抗。因此，感觉结构的阻抗可以与弹性皮肤的阻抗匹配。基于触觉小体卷曲神经结构的这两个特性，提出了仿生卷曲触觉传感器。
In this paper, we investigate the roles of helical nerve axons of Meissner corpuscles, one of the mechanoreceptors for human tactile sensation. Two properties of the coiled structure for detecting the mechanical deformation of an elastic skin are shown. Firstly, the coiled structure has a property of transforming of shear and stretch deformations of the elastic skin into stretch and shear deformations of the surface of the line of the coil. In essence, stretch and shear deformations are tranposed by the coiled structure. Thus, the transducers on the surface of the line of the coil can separately detect stretch and shear deformation of the elastic skin. Secondly, the impedance of the coiled structure is much smaller than the impedance of the line of the coil itself. Therefore, the impedance of the sensory structure can be matched to the impedance of the elastic skin. Based on these two properties of the coiled nerve structure of the Meissner corpuscles, biomimetic coiled tactile sensor is proposed.
